6. The barred pattern of chicken feathers is inherited by an X-linked gene. The dominant allele, $$X^B$$, causes barring and the recessive allele, $$X^b$$, causes no bars. In poultry, females are XY and males are XX. a) A non-barred rooster is crossed with a barred hen. What are the genotypes and phenotypes of the offspring? b) A heterozygous barred rooster is mated with a non-barred hen. What genotypes and phenotypes will occur in the offspring?

Step 1

The problem states that the barred pattern of chicken feathers is inherited by an X-linked gene. Dominant allele: $$X^B$$ (causes barring) Recessive allele: $$X^b$$ (causes no bars) Crucially, in poultry, sex determination is different from mammals: Females are Show more…
