A fruit fly with a black body and red eyes mates with a fruit fly with a brown body and
brown eyes. The offspring all have brown bodies and red eyes. When the offspring mate
with each other, they produce some flies with black bodies and brown eyes and some
with brown bodies and red eyes. They also produce offspring that resemble the original
pair of flies. Why does the third generation of flies have combinations of traits that
were not seen in the first generation?
A The alleles for the traits are recessive.
B
The alleles for the traits are dominant.
C
The alleles for the traits assort independently.
D
The alleles for the traits develop mutations.
