The frequency of individuals with the dominant phenotype is 0.83.
Explanation:
We are provided with:
Black allele has completed dominance over brown allele
T. no of dogs (dominant)= 2000
No. of black dogs (dominant) = 1660
From Hardy-weinberg equilibrium
Frequency of individual - (individual/ Total population)
Frequency of black dogs = 1660/2000 =
0.83
So, The frequency of individuals with the dominant phenotype is 0.83
