Respuesta :
In chickens, the allele for black feathers is co-dominant with the allele for white feathers. Black-feathered and white-feathered birds are homozygotes for either the black (B) allele or the white (W) allele. The genotype of an offspring of a black rooster and a white hen is heterozygous and has a genotype of (BW). The phenotype of the offspring shows some with white and some with black.
Explanation:
Co-dominant alleles cannot mask one another’s expression. This results when an allele from each of the homozygous parent are combined. The offspring produced will have phenotypes from both the parents and hence becomes heterozygous.
Hence the offpsring’s genotype produced by combining a co-dominant black rooster and a white hen becomes heterozygous and will demonstrate features (phenotype) with both black and white feathers.
The branch of science which deals with genes and inheritance is called genetics.
The correct answer for the following is:-
- Pure breed
- Impure breed
- Genotype
- Phenotype
- White and some with black.
Co-dominant alleles are defined as an allele that can not dominate their effect on the other parents. This results when an allele from each of the Pure parents is combined and formed a hybrid result having both characters.
Hence, the correct answer is In chickens, the allele for black feathers is co-dominant with the allele for white feathers. Black-feathered and white-feathered birds are Pure breed for either the black (B) allele or the white (W) allele. The genotype of an offspring of a black rooster and a white hen is IMPURE Breed and has a genotype of (BW). The Phenotype of the offspring shows black and white
