The maternal-effect mutation bicoid ( bcd ) is recessive. In the absence of the bicoid protein product, embryogenesis is not completed. Consider a cross between a female heterozygous for the bicoid alleles ( bcd + / bcd - ) and a male homozygous for the mutation ( bcd - / bcd - ).
(a) How is it possible for a male homozygous for the mutation to exist?
(b) Predict the outcome (normal vs. failed embryogenesis) in the F 1 and F 2 generations of the cross described.
