Document Summary
I haven"t quite told you the truth . we have not seen the end of independent assortment quite yet . we do need to cover a few more aspects of it Today we will complete the coverage of (simple) multiple gene inheritance . simple in the sense that we are not working with linked genes, or cases where environmental variation can make it difficult to detect the effect of individual genes. 1 of those in the nucleus but in this case, the underlying mechanism differs from that of simple meiosis with separate. Independent assortment leads to genetic recombinationin the f2 progeny there are new combinations of traits present combinations that were not present in the parental generation genetic recombination is essentially an outcome of sexual reproduction! In the 1970"s evolutionary biologists began to recognize that the production of males in sexual populations entails a kind of cost.
