In Leghorn chickens colored feathers are produced by a dominant allele, C; white feathers are produced by the recessive allele, c. The dominant allele, I, of another independent gene inhibits expression of color in birds with geno-types C/C or C/c. Consequently the C/_ I/_ genotype and the c/c _/_ genotype […]
