In fruit flies (Drosophila melanogaster), the inheritance of wing type is controlled by a single gene with two alleles. The allele for normal wings (VVV) is dominant to the allele for vestigial wings (vvv).
In a first 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 cross, two heterozygous fruit flies (VvVvVv) 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.
