If a homozygous white horse c"cW and a homozygous black horse CBCB are bred together, what is the likelihood that their offspring will be roan with both colors represented in their hair if this gene follows a codominant inheritance pattern? (1 point)
If the gene follows a codominant inheritance pattern, the offspring will inherit one allele from each parent. In this case, the possible combinations for the alleles are: C"C and CBCB.
Since both alleles are codominant, the offspring will display both colors in their hair. Therefore, the likelihood that their offspring will be roan with both colors represented in their hair is 100%.
In a codominant inheritance pattern, both alleles are expressed in the phenotype, resulting in a roan coat color when a homozygous white horse (c"cW) is bred with a homozygous black horse (CBCB).
To determine the likelihood of offspring being roan with both colors represented in their hair, we need to consider the possible genotypes of the offspring when these two horses are crossed.
The genotype of the offspring will depend on the alleles received from each parent. Since both parents are homozygous, each offspring will receive one allele from each parent. The possible combinations are as follows:
Offspring genotype:
- cW from the white horse (c"cW)
- CB from the black horse (CBCB)
The possible combinations of alleles in the offspring are:
- cWCB
- cWCB
Since both alleles (cW and CB) are codominant, both colors will be represented in the hair of the offspring. Therefore, the likelihood of the offspring being roan with both colors represented in their hair is 100%.
Please note that this analysis assumes a simple Mendelian inheritance pattern and the absence of any additional genetic factors that may influence coat color.
To determine the likelihood of the offspring being roan with both colors represented in their hair, we need to first understand the concept of codominant inheritance.
Codominant inheritance occurs when both alleles of a gene are expressed equally in the phenotype of heterozygous individuals. In the case of horses, the gene that determines coat color has two alleles: "cW" for white coat color and "CB" for black coat color.
When a homozygous white horse (c"cW") is bred with a homozygous black horse (CBCB), all their offspring will be heterozygous for the coat color gene, carrying one allele for white coat color and one allele for black coat color (cWCB).
Since this gene follows a codominant inheritance pattern, the offspring will exhibit both colors equally, resulting in roan horses. Therefore, the likelihood of the offspring being roan with both white and black colors represented in their hair is 100%.
