What is the genotype of a red and white chicken?

What is the white chicken’s genotype?

2. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.

What is a hens genotype?

Chickens have 39 pairs. Genotype—The genetic makeup of an organism. … Examples of aspects of a chicken’s phenotype include body shape, feather color, eye color, comb type, and so on.

What are the genotypes if you cross a black chicken and a white chicken?

On mating a black chicken with white chicken, the offsprings will inherit B allele from black parent and W allele from white parent. The genotype of offsprings will be BW.

What is the genotype of black chicken?

Answer: In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.

What is the genotype for red Cow?

When purebred red cattle (genotype CRCR) and purebred white cattle (genotype CWCW) are bred, the offspring carry the genotype CRCW. The genotype expresses as red roan because the offspring have both red and white hairs.

How many chromosomes do chickens have?

The chicken karyotype comprises 39 chromosome pairs as follows: 10 pairs of large autosomes (chromosomes 1-10), 28 pairs of microchromosomes (chromosomes 11-38), and a pair of sex chromosomes (chromosomes W and Z).

What is the genotype of the hens genotype?

What is the hen’s genotype? rooster; BB hen: WW.

Is black or white dominant in chickens?

In poultry genetics, both black (BB) and white (WW) are dominant. So breeding a black rooster with a white hen would result in a black-and-white chicken.

What is the genotypic ratio of this cross?

The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a lethal allele.
