Document Summary
A genes position can be used to define it at the dna level. Understanding it s function: the genes present and their arrangement on chromosomes are often slightly different in related species. By comparing these differences, scientists can deduce the evolutionary genetic mechanisms through which these genomes diverged--> useful in interpreting mechanisms of evolution. Independent assortment of genes on different chromosomes at meiosis (one way to ""shuffle"" allele combinations. Compare the inputs into meiosis w the outputs. 4. 1 diagnostics of linkage: recombination maps are assembled 2 or 3 genes at a time using linkage analysis. If two genes are linked --> loci of these genes are on the same chromosomes and therefore the alleles on any one homolog are linked by the dna between them. Independent assortments weren"t coming up as the predicted 9:3:3:1 ratio: morgan"s test cross = important.
