Answer:
Total four genotypes and its frequency
SsWw – 4/16
ssWw- 4/16
Ssww - 4/16
ssww - 4/16
Phenotype –
SsWw – Heterozygous Spotted skin and heterozygous wooled hair
ssWw - Homozygous non-spotted skin and heterozygous wooled hair
Ssww - Heterozygous Spotted skin and Homozygous non -wooled hair
ssww - Homozygous non-spotted skin and Homozygous non -wooled hair
Explanation:
Given -
Allele for spotted skin is "S"
Allele for non-spotted skin is "s"
Allele for Wooly hair is "W"
Allele for non-wooly hair is "w"
Allele "S" is dominant over "s"
And Allele "W" is dominant over "w"
Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman
Genotype of heterozygous spotted, non-wooly man - Ssww
Genotype of heterozygous wooly-haired, non-spotted woman - ssWw
