Question

genetic factors in inheritance quick check
if a homozygous white horse $c^{\text{w}}c^{\text{w}}$ and a homozygous black horse $c^{\text{b}}c^{\text{b}}$ 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)

Explanation:

Step1: Identify parental genotypes

Homozygous white horse: $C^WC^W$; Homozygous black horse: $C^BC^B$

Step2: Determine gametes each parent produces

White horse gametes: all $C^W$; Black horse gametes: all $C^B$

Step3: Predict offspring genotypes

All offspring inherit $C^W$ and $C^B$, so genotype is $C^WC^B$

Step4: Apply codominance rule

In codominance, $C^WC^B$ expresses both traits (roan). All offspring have this genotype.

Answer:

100%
