Paul Andersen introduces the Punnett Square as a a powerful tool in genetic analysis. He tries to address major misconceptions that students have when use a Punnett Square. He gives a number of examples of monohybrid crosses and one example of a dihybrid cross. The square is a simple tool that uses the outcome of meiosis to determine possible offspring in a cross.

@gamingtec101 8 лет назад

+Victoria Jaimes my teacher made us watch a video that Even i could do better!!!

@liganjinxeseverything3174 8 лет назад

I agree. I don't even study genetics yet and it makes sense 😆. Well, maybe my mathematics has something to do with it...

@sovereignviper 8 лет назад

+Victoria Jaimes Exactly. This is the problem with the education system. I'm likely going to fail biology because to professors nowadays everything is a big joke. This video is amazingly clear and professional compared to what modern college professors are doing

My god, why can't all bio teachers put some emotion into their voices like this when they teach? Bozeman is the first one I've heard that doesn't sound like a monotone robot. Can't tell you how much I appreciate that Bozeman, thank you so much for this helpful video!

@amyrose45876 10 лет назад

My teacher gives A LOT of emotion in his voice :P

@Aliaisawesomeable 10 лет назад

Seriously? I'm so jealous. ;P

@gamerroyal659 10 лет назад

Ana Lin totally agree with you my bio teacher sounds like a robot too only when she looks at you its like the terminator is there

@Aliaisawesomeable 10 лет назад

That sounds quite terrifying, but at least there's something there to keep your mind awake & alert for.

My teacher is a legend who actually explained it right and then gave us this vid if we had any troubles at home.

@ajhowell7672 7 лет назад

You're the only reason I'm going to pass my test tomorrow. I wish you were my bio teacher. She goes so fast and yet takes a week to teach this, and you teach it in 12 minutes. Your the goat mr Bozeman plz keep doing this for as long as you live.

What a useless teacher!! . He shouldn't even be teaching then !!

@allzzjn 5 лет назад

I relate. She just showed us a picture of a punnett square, said, "This is how it's done," and made us answer a whole test right after. Also, she is not good at explaining. Not at all.

@QueenBeeTV88 4 года назад

He doesn't want you to learn so you won't take his job :D

@jenniferbostrom2679 7 лет назад

Day before test, this helped me so much because before I didn't understand the function of the Dihybrid cross but now I do! Thank you.

@Sandra-fj3ou 4 года назад

It's so helpful. I watched 3 or 4 videos about Punnet Square before I watch this one, and I cannot really understand thing, it's so logic tho. Then I saw this one, and watched it. So helpful for someone that English is not your original language. Because the words is not really difficult to understand. Hope someone see this comment will has a great grade on both their test and homework. 🤗

@thegmanofEAP 9 лет назад

Just wanted to throw a big thanks your way! My professor, bless her heart, jumps through and over complicated stuff like this, and you've really helped me to grasp this in a way that's not all that complicated.

@melissaperrin1554 5 лет назад

Mr. Anderson, Thank you for your clear lectures. I really have appreciated both your chemistry and biology video!

great thats so awesome. How about you roll all those thoughts up and put them in the bin.

@Akosilors 12 лет назад

When my teacher asks me how I got this before we even started this lecture, I'm gonna say Mr. Andersen taught me. XD

@emiajyduj 11 лет назад

I love the way that you always have a background information before getting into subject, thank you Mr. Anderson:-)

@sarahcalderon1902 11 лет назад

@jamesmyers2087 6 лет назад

I am an older student in an art major curriculum retaking biology because... not really sure. Maybe the school thought it might help me mix egg tempura colors. It's been a running firefight to maintain the grade average I need and more of a challenge than I thought I'd have. But I just want to say that quite a few of the cell division, reproduction and genetic topics were so much easier coming from your videos than the McGraw Hill textbook. You've got a real gift for instruction. Owe you big time and thanks.

@TheCraziwhitegirl 10 лет назад

Oh my gosh, thank you SO SO SO much for this video! My teacher is really lazy and just hands out worksheets and expects us to already know the information. I have a test tomorrow on this and you made it really simple for me. :)

@ilovealfieboe11 11 лет назад

Thank you so much! Before I watched your video, I was so confused regarding dihybrid crosses and how to set them up, etc. Now, I am a lot more confident about them and for the first time am not dreading my biology test. You've earned yourself a new subscriber. I'll be sure to share this video... thanks again!

@tenzzomkyi 9 лет назад

ohhh.. the last one is a 4X1 punnet square since rryy's only possible gamete is ry, and RrYy produces Ry, rY, Ry, AND ry

@salami99 7 лет назад

Yes, and that means is a 1:1:1:1 ratio. That answer is accepted on the Free Response math.

@sweetangel9340 2 года назад

Omg thank you!!! You saved my science homework

@wolvina 9 лет назад

Wouldnt the square be 1X4 ? Since RrYy can produce 4 different letter pairs ( RY, Ry, rY,ry), and rryy make one possible pair ( ry) ? so would it be geno rate = <a href="#" class="seekto" data-time="62">1:2</a>:1 and pheno rate <a href="#" class="seekto" data-time="62">1:2</a>:1? I could be totally wrong....
