owl, barring (B) is sex linked and dominant recessive allele (b) producing solid black color when homozygous. Silky feathers (s) is a recessive autosomal gene as opposed to non-silky (S). If black cocks, heterozygous for non-silky, are crossed to barred, silky hens, what genotype and phenotype will be produced
In owl, barring (B) is sex linked and dominant recessive allele (b) producing solid black color when homozygous. Silky feathers (s) is a recessive autosomal gene as opposed to non-silky (S). If black cocks, heterozygous for non-silky, are crossed to barred, silky hens, what genotype and
(Sex-linked genes can be written as XAXA for female and XAY for male since superscript function is not available)
- If the genotype of the cock? SsXbY
- The possible genotypes of the hen are ssXBXB, ssXBXb
- Write the genotype of the F1 when the hen is homozygous dominant for barring are SsXBXb, SsXBY, ssXBXb, ssXBY
