In fruit flies (Drosophila melanogaster), the inheritance of wing shape is controlled by a single gene with two alleles. The allele for normal wings (WWW) is dominant to the allele for vestigial wings (www).
In a first genetic cross, a heterozygous parent mates with a homozygous recessive parent. State the genotypes of both parents.
State the potential phenotypes of the offspring from this cross.
In a second genetic cross, two heterozygous fruit flies (WwWwWw) mate. State all the possible genotypes of their offspring.
Calculate the probability that a single offspring from this second cross will have normal wings. Give your answer as a percentage, fraction, or decimal.
