In Drosophila melanogaster, ebony body color is determined by the e allele. The e+ allele produces the wild-type honey-colored body. In heterozygotes, the body is honey-colored except for a dark marking called the trident seen on the thorax. The e+ allele is thus considered to be incompletely dominant to the e allele. a. When female e+ e+ flies are crossed to male e+ e flies, what is the probability that progeny will have the trident marking? Animals with the marking mate among themselves. Of 100 progeny, how many would be expected to have a trident, how many would have ebony bodies, and how many would have honey-colored bodies?

Question

In Drosophila melanogaster, ebony body color is determined by the e allele. The e+ allele produces the wild-type
honey-colored body. In heterozygotes, the body is honey-colored except for a dark marking called the trident seen on the thorax. The e+ allele is thus considered to be incompletely dominant to the e allele.
a. When female e+ e+ flies are crossed to male e+ e flies, what is the probability that progeny will have the trident
marking? Animals with the marking mate among themselves. Of 100 progeny, how many would be expected to have a trident, how many would have ebony bodies, and how many would have honey-colored bodies?
