Question

The narrow-sense heritability of ear length in Reno rabbits is 0.4. The phenotypic variance (VP) is 0.8, and the environmental variance (VE) is 0.2. What is the additive genetic variance (VA) for ear length in these rabbits?

Answer 1

The additive genetic variance (VA) for ear length in Reno rabbits is 0.32.

Step-by-step explanation:

The additive genetic variance (VA) can be calculated using the formula:

VA = h2 x VP

where:

• VA is the additive genetic variance
• h2 is the narrow-sense heritability
• VP is the phenotypic variance

Plugging in the given values, we have:

VA = 0.4 x 0.8 = 0.32

Therefore, the additive genetic variance for ear length in Reno rabbits is 0.32.
