  @crackit

just for an explanation.. for 12/4/36

choice B-- random segregation --


In meiosis what is random segregation?

When homologous chromosomes enter different gametes, there is no way of telling which chromosome (and, therefore, which genes) will end up in which gamete.

If G and g are two genes on homologous chromosomes, G has as much chance of ending up in one particular sperm cell as g does.

Mendel recognized that if he picked up one pollen grain, it might contain a P allele or it might contain a p allele; there was no way of telling because it was all random.
