platinum color in foxes is produced by heterozygous genotype Ss, and silver foxe

Question

platinum color in foxes is produced by heterozygous genotype Ss, and silver foxes are the genotype SS. The genotype ss is lethal, and the fox dies in early embryonic development. In a group of foxes, 30% are platinum and 70% are silver
a)What are the estimated frequencies of the S and s alleles in the above group of foxes?
b)If this group of foxes were mated, what are the frequencies of the two colors observed in the cubs that are born?
c)What are the frequencies of the S and s alleles in the cubs?

I wanna understand how to solve this not just the answers if possible please.

Explanation / Answer

platinum color in foxes is produced by heterozygous genotype Ss,---------- 2PQ=

and silver foxes are the genotype SS--------- P^2

. The genotype ss is lethal, --------- Q^2

and the fox dies in early embryonic development.

In a group of foxes, 30% are platinum and 70% are silver

P^2+2PQ+Q^2

BY USING GENE COUNT METHOD=

DOIMANANT ALLELE= D+ 1/2H

=0.3+0.7/2= 0.3+0.35=0.65

ACCORDING HARDY WIEN BERG

P+Q=1

RECESSIVE ALLE;E s= 1-p= 0.35
a)What are the estimated frequencies of the S and s alleles in the above group of foxes?

frequencies of the S alleles=0.65

frequencies of the s alleles=0.35
