It has been shown by Belyaev and Trut that foxes can be domesticated, over the time of various generations, by selecting and mating animals with certain traits, like responses to feeding, handling, and others.

A sustained multi-generational association in which one group of species presumes a substantial extent of effect over the care and reproduction of another group to secure a more predictable supply of resources from that latter group is known as domestication.

In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If a red-eyed heterozygous f

ladessa [460]

The answer is Rr and rr.

We know:
r - recessive allele
R - dominant allele
RR - dominant homozygote with red eyes
Rr - heterozygote with red eyes (since one dominant allele R can mask recessive allele r)
rr - recessive homozygote with sepia eyes

Heterozygote Rr can give to the offspring either dominant allele R or recessive allele r. Recessive homozygote rr can give to the offspring only recessive allele r (take a look at the uploaded image of Punnett square).
After crossing the parents:
Parents: Rr x rr
Offspring: Rr rr Rr rr

So:
2 out of 4 offspring will be with heterozygous with red eyes Rr: 2/4 = 0.5 = 50%
2 out of 4 offspring will be with homozygous with sepia eyes rr: 2/4 = 0.5 = 50%
