When male mice heterozygous for a small deletion on Chromosome 2are mated to normal females deletion-bearing offspring have thinbodies and are slow-moving while non-deletion-bearing offspringare normal. However when females heterozygous for the samedeletion are mated to normal males all offspring are normal. a.What mechanism likely explains this pattern of transmission? 1 ptb. Provide an explanation for the observed phenotypes. Why wouldoffspring of females heterozygous for the deletion have normaloffspring while those of males heterozygous for the deletionproduce a mixture of affected and unaffected progeny?
