USMLE STEP 1: GENETICS (THE BASICS) w/ Questions 

My step prep is divided mostly between this channel and dirty medicine. Thank u both u angels!

Thank you SO much! This type of flowchart method is exactly what I was hoping for. Undergrad genetics was a long time ago. I really appreciate you asking for input on video topics.

Bless you!! I could never get this down. SO helpful. Thank you, Dr. Neil!!

Thank you for always taking the time to do these for us. You probably don’t know how many lives you inspire and motivate every day. There’s lots of us out here! Can you touch more on pharmacology?

I cannot think of a better way explaining this.You are truely a blessing!!

I saw your Biostat videos years back,arguably best for step 1.Hope you make videos more often,they are so helpful.

This is crystal clear! Thank you Dr. Randy.

My brain is so happy right now . Man thank you very much .

One of the best videos on genetics i have seen so far. THANKYOU Dr. Randy Neil :)

Excellent explanation! Thank you so much!

Randy, this is Kosher✨✨✨ Thanks. It really filled in the blanks for me.

you are the best , never really learned until now

thank you Dr. Randy for these videos

Thanks Dr.Randy!

Thank you so much for your time creating this video and explaining the pedigree in a simple way. It is easy to digest :)

Randy Neil is a good teacher!

HI Dr Randy most simplified genetics video thank you :)

Couldn`t be better than this. Thank you very much.

Genius and simple! love it.

This was great Doctor.. I found about you late(just 1mth to go for my step 1) but I am glad I eventually did find you

Your videos are very helpful Dr. Neil. Thanks so much.

Great video! Thank you very much!

You have a great talent of explaining concepts. Please keep making videos. Big THANK YOU 🙏

As a someone who is mathematics illiterate, I literally exclaimed 'BEAUTIFUL' at 15:15. Thank Dr. Neil

Thank you dr Neil. More than useful.

WOWWW .. can't even explain how easy you made the pedigree chart look.. never felt it could be this easy. Where were you all my life- all my 'studying for medical exams' life . I am a family physician from UK now in NY and have been avoiding giving my step 1 - now I am super confident I can prepare all the difficult topics using your videos. So helpful.thankyou. Is there a way I can get all your videos as sometimes they don't appear on youtube although I have subscribed to you also !

Hi Randy Neil ....its so wonderful to learn from u and i really want to make a video on risk recurrence in genetic disorders ...its a request plzzz

I just realized that you have videos in genetics 😊thank you so much your biostatistics videos help me a lot ,God bless you please make more videos with questions

6:36 The pedigree on the left also meets the criteria for autosomal recessive. The portion on the right shows us that both parents are homozygous and thus express the trait, so all their offspring have nothing but that allele and also express the trait

This is GOLDEN!

Thanks .👍🏼👍🏼u make everything simple and easy... even though it’s not an easy topic.,, but u knw how to tackle this.... thanks...

That was surpringly really really good..you nailed it .👍

Excellent, Dr. Tks a lot

This was extremely helpful. Thank you for making everything simple

Thank you so much for pedigrees, you make simple and easy for us.

You are a saviour..... thank you so much 😊

It was very helpful to clear the concepts.Thanks Dr.Neil.

Thank you Dr. Neil , it’s a great illustrative video! You have a direct no bs approach that simplifies confusing topics. I watched your first two Biostat videos and they helped me out a lot. Thanks again Dr. Neil. 👍

Thank you for everything.

Simply amazing

You have changed my life.

You are amazing may you be blessed

wow this video explains it in so easy ways. thank you doc.

That moment when you think you got it ALL DOWN, I always realize that there is MORE TO LEARN! haha Wonderful video! both parts of the genetics series are very very helpful! Also a different approach which I truly appreciate! Yours is a lot more simplified!

Thank you! One little question. What is the rule to make the decision at 6:21? I mean how do you deside wich part (left or right) not to consider?

We say “You put dots over the letters” that’s enough. You are the best.

wowww this saved me!! I haven't even completed the video yet already feeling grateful. Thank you Sir.

Thanks a ton 😀

Amazing!!

Thanks doc!

Thank you so much:) I am waiting for ur video.It is super helpful

Thanks Doc! Like always great video I've been reading that the examen is giving more space to "Population Pyramids" and "Lymphatics". Maybe you can touch any of those topics? Thanks in advance!

You’re not just an amazing, smart teacher but also an incredibly mellow soul. Thank you for making these videos! 🙏😊

Hi Dr. Randy, Thank you for sharing your knowledge with us. Your videos are very helpful, to the point, clearing concepts, easy to understand, quick problem solving. You are doing a great job, your way of teaching is simply amazing and friendly that shows your passion to help us. I really appreciate your work. Can you also share your every lecture sheet with us like you uploaded biostatics's sheet on your website (That's also a very helpful video). Your lecture's laminated sheets will be a great help for quick review. GOD bless you.

SO helpful, thank you! The summary sheet at the end is not on your website, do you have a clearer picture of it or could you post it, please?

wow Genius, just G E N I U S! thanx so much doctor

thank you doc

thankyou rendy neil !

Very Helpful

Thanks a lot sir, really appreciated 💕💕💋💋

Gold.

Thank you very much for nice explanation

It is said that Diabetes is Mitochondrial or Dominant X linked from father to daughter. But diabetes is recessive based on obesity accordingly. Please advise on your thoughts Randy. Thank you!

its amazing way👍👍

Brilliant

thank you! your video helped me alot

thankyou for helping out genetics. I was looking of the video on Hardy weinberg equation, am not able to find it here, could you please re upload it???

great

Thank you 🤗🤗🤗🤗🤗

Could you put up a picture of the division of disorders that you have laminated please?

Thanks sir..😊

Thank you so much for your videos. Do you have any videos on general principles of genetics sir?

sir please do one more video just on probability questions that include hardy-weinburg equation..there is so much variation in these qs.,...and one video for bacterial/viral genetics....we shall be grateful.

Dear Dr. Neil, Thanks for your video first of all. I wanted to ask you: Is the pedigree in the question at 13:00 really only X-Linked dominant? Couldn't it also be an autosomal dominant inheritance? There is a 50% chance that the male patient in the first row inherited his dominant autosomal chromosome to his kids - by incidence only to his daughters. I am especially concerned because one of his sons has children with a women that seems to have the same disease - she inherited her allel to both male and female kids. Of course this could be X-linked dominant too but I think it could also be autosomal dominant. What do you think? Best, Jan

Could you please share that spreadsheet that you made for yourself and laminated it ? Ill be really thankful to you

Hi. Thank you for the video. just a question. the last question it asked the chance of being a carrier. first aid does say 50 % because AA means they are not carrying the disease. just want to know if I'm learning it right. Can you clarify please?

omg I just realised all this time I understood wrong .. thank you sir for making it so easy .

Hey. Thankyou for the great video❤Can you please make a video on how to solve Hardy weinberg questions in step1😭

Is there a list of common conditions and the inheritance patterns? Is his notes uploaded anywhere?

What else do you want when you got the best ,thank you so much

thank you doctor ... you just made it simple

Hi, where can I get your chart, laminated sheets?

A father has diabetes not overweight and no one else in his family line has it prior or in the now. Years later a daughter is diagnosed with diabetes AFTER bearing children with a male who is diabetic she never had any complications diagnoses prior with her children from a previous marriage only AfTER-later in life when encountering a male who has a family history of diabetes. The mother then has a daughter from the previous marriage where no diabetes existed becomes diagnosed with diabetes after a pregnancy. No other siblings has diabetes no other family members has diabetes still. Even the children who comes from the male with a family history of diabetes. Later the first marriage father becomes diagnosed with diabetes not linked to anyone in his entire family later in his life after 50. ??? None are obese. Please explain this complexity of diagnosis.

Nice presentation, makes things easier, thanks. I have a question, if it skips generation then why we have to rule mitochondrial first ? In other words, do mitochondrial diseases skip generation?

Dr. Neil. Where did you get the pneumonic from for the disease per inheritance? ?

Thanks Dr Neil. Anytime I watch your videos , I get the answers right before you explain , I just don’t know why I perform poorly on my nbmes. My exam is in 4weeks and I’ve no idea what to do again 😫

where can i find this chart in this video?? I have to make same

Hello sir, can I get the picture of the laminated sheath please

Are the notes sheet for this uploaded on your web page?

Hi Dr.Neil , Can we purchase that lamented chart or do you share it with students ?

Thank you so much ❤ may I know where I can find the chart you prepared?

Thank you so very much🙏🙏💐💐 for the most beautiful explanatory video 👏👏💐💐 it is highly appreciated! I have 3 months left for my exam but I am worrying more than studying 😥😥 is it possible please; you share your experience such as schedule and plan of working on UWorld questions thanks in advance
