Like dorsal,bicoidis a strict maternal-effect gene in Dro-sophila; that is, it has no zygotic expression. Recessive mutations in bicoid(bcd) cause embryonic death by pre-venting the formation of anterior structures. Predict the phenotypes of

(a) Bcd/bcdanimals produced by mating heterozygous males and females;

(b) Bcd/bcdanimals pro-duced by mating bcd/bcdfemales with  bcd/+males;

(c) Bcd/+animals produced by mating bcd/bcdfemales with bcd/+males; 

(d) Bcd/bcdanimals produced by mating bcd/+females with bcd/bcdmales; 

(e) Bcd/+animals pro-duced by mating bcd/+females with bcd/bcdmales.
