Question

In a population of weasels, black (R) is the dominant color and white (W) is the other dominant trait. In weasels, fur color follows a pattern of codominance. The heterozygous genotype produces black and white spotted weasels. Consider the genetic cross shown in Punnett square. If there are 60 baby weasels born as a result of the cross, how many should be spotted?

A) 15
B) 20
C) 30
D) 60

Answer 1

30 of them should be spotted I believe. I am not 100% sure, but to me, that seem like the best answer.

Answer 2

Option D

Step-by-step explanation:

It is given that both the black and white fur color are dominant color. Also, in weasels, fur color follows a pattern of co dominance.

When a cross is carried out between a true breeding black weasel with genotype (RR) and true breeding white weasel with genotype (WW), then heterozygous species of weasels with genotype (RW) will be produced. This genotype leads to black and white spotted weasels because of co dominance.

Hence, option D is correct
