Yоu аre studying twо linked genes in lizаrds. Yоu hаve two females, and you know that both are the same genotype, heterozygous for both genes (A/a and B/b). You testcross each female to a male that is fully homozygous recessive for both genes (a/a and b/b) and get the following progeny with the following phenotypes: Female 1 Female 2 AB – 37 AB – 5 ab – 33 ab – 4 Ab – 4 Ab – 35 aB – 6 aB – 36 How can you explain the drastic difference between these two crosses?
