the allele for white fur is revessive and the allele for normal fur is dominant the frequency for the normal fur allele is 0.60.
Mariulka [41]

Answer:

36% of wolves have normal fur.

Explanation:

Given , the allele for white fur is recessive and the allele for normal fur is dominant

Let "N" represents the allele for normal fur and "n" represents the fur for white fur.

As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"

Given ,

p = 0.60\\

Then frequency for dominant genotype will be "p^2"

p^{2} \\0.60^2\\0.36

Percentage of the wolves with normal fur is

0.36*100\\= 36%
