If a homozygous white horse CWCW 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) Responses 25% 25% 100% 100% 50% 50% 0% 0%

In this scenario, we have a homozygous white horse (CWCW) and a homozygous black horse (CBCB). The coat color gene follows a codominant inheritance pattern.

When these two horses are bred together, the offspring will inherit one allele from each parent:

  • From the white horse (CWCW), the offspring will receive a C allele (C for white).
  • From the black horse (CBCB), the offspring will receive a C allele (C for black).

This results in all offspring being heterozygous (CWCB). In codominance, both alleles are expressed equally, so the offspring will display a roan coat, which is a mix of both colors.

Therefore, 100% of the offspring will be roan.

The likely correct response is: 100%.
