Crossing over animation - This lecture video explains about DNA recombination and linkage mechanism. The provisions of chromosome mutation in this segment within the chromosome breaks are two ends changes orientation by 180° will integrate into the same chromosome there are two types of versions appear eccentric and version includes the centromere in the inverted segment and repair centre conversion does not include the centromere general generic material is neither gained more last in an inversion individual who is heterozygous for the Perry centre conversion has chromosome with the normal order of genes and the other chromosome with an inverted segment the homologous chromosomes pair to the best of their ability in meiosis and this means that the pairing of the inverted segment with the normal segment will produce a loop called an inversion loop the problems arise when a crossover occurs within the inverted segment between chromosome' sound during meiosis crossovers can give rise to viable and viable gametes if a single crossover occurs within the inversion loop for different chromosomes are produced the first chromosome were no crossover event occurred has will order of genes this is a viable gamete this chromosome was involved in the crossover it lacks genes EFG and H and is duplicated 14 a due to the deletions and duplications that produced is in a viable method chromosome was not involved in the crossover this chromosome is identical to the original parental inverted chromosome because it contains all the genes even though they are in a different order the gamete with this chromosome is viable the first chromosome was also involved in the crossover is likely a gene and is duplicated for genes EFG and H due to the deletion and duplications is also produces in an viable gamete in salary is crossover event within a heterozygous Perry centre conversion gives rise to 2 viable and to viable gap. Thank You for watching our videos from Biology Animation Videos channel. This channel is created to compile animated biology lectures and videos from different animation sources. None of these videos are created by us. we just organize them and place them in RU-vid for your understanding so If you want to know details about these animation please see the credit section for knowing the original content developer and please convey privilege and gratitude to them. Thank You.
