Question

The allele for black fur (B) is dominant to the allele for white fur (b) in rats. If you have a black rat and you want to know it s genotype (whether it is BB or Bb), you could perform a testcross. Please tell me what kind of rat (what color) you would mate your black rat with in a testcross. Explain what results you will get if your unknown black rat is BB, and explain how this differs from the results you will get if your unknown black rat is Bb. How will the results help you to determine the genotype of your black rat?

Answer 1

honestly

Step-by-step explanation:

I think it would end up being a black rat since black rats have more power then others.
