assistance relative to independent assortment

[sillysmile]

Hi there, I was hoping that somebody could explain the concept of independent assortment to me, so that I can better understand it.
(I'm highly thankful for help + understanding independent assortment) - previously not understanding = +1karma   :crazy2:

yes, I'm aware that my topic/post is confusing/crazy.

Independent Assortment is where the alles of one gene may combine with the alles of another gene in the gametes. So basically.. these genes are on different chromosomes, they are not linked so when crossing over occurs they distribute evenly and are not dependent on each other.

Independent Assortment is when two genes are not linked - either on separate chromosomes or more than 50 map units apart on the same chromosome. So during meiosis, when the chromosomes duplicate and then separate, the alleles you're considering are equally likely to segregate in one combination as another. So you're just as likely to get AB gametes as you are to get ab, Ab or aB gametes.

If the genes do not assort independently, it's because recombination between chromosomes is changing the ratios of gametes present.
