NettetA crossover frequency between 0 percent and 50 percent indicates that the genes are on the same chromosome and crossover occurs some of the time. In a test cross for two characteristics such as the one shown here, can the predicted frequency of recombinant offspring be 60 percent? Why or why not? No. NettetRecombination in the form of crossing over occurs between homologous chromosomes, in order to increase genetic diversity by changing the assortment of genes. It does not violate independent assortment since it doesn't affect how traits and genes are actually assorted in gametes. cobby badger ventures https://catesconsulting.net
