In fruit flies (Drosophila melanogaster), the
bn+ allele for normal dull red eyes is dominant
to the bn allele that gives brown eyes. Another gene
affects wing shape; for this gene, the ct+
allele for normal wings is dominant to the ct allele,
which gives “cut” wings, with jagged edges. A fly with dull red
eyes and normal wings was crossed with a fly that had dull red eyes
and cut wings, and the following progeny were obtained:
16 dull red eyes, normal wings
14 dull red eyes, cut wings
5 brown eyes, normal wings
5 brown eyes, cut wings
What were the genotypes of the parents?
Please show cross!!
