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 (Aa and Bb). You testcross each female to a male that is fully homozygous recessive for both genes (aa and bb) and get the following progeny with the following phenotypes:                                              Female 1     Female 2                                               AB – 3          AB – 50                                               ab – 3           ab – 49                                               Ab – 45         Ab – 5                                               aB – 52         aB –3 How can you explain the drastic difference between these two crosses?
