Both parents were heterozygous (Bb). The offspring would statistically be: BB, Bb, Bb, and bb. All but the bb offspring would be black and the bb would be brown.
Both alleles for feather color are dominant.
The offspring will likely be a mix of black and white feathers, as erminette coloring is a pattern that combines both black and white. The specific distribution of colors will depend on the genetics of the parent chickens.
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
