The variance in tail length in a large population of genetically diverse mice is found to be 21.30.The broad-sense heritability for this trait in an identical population was found to be 0.8.Based on this information,what is the predicted genetic variance (V_g)for these mice? A)4.26 B)17.04 C)20.50 D)21.30 E)26.62

The predicted genetic variance can be calculated using the formula:
VG = H2 * VP
where VG is the genetic variance, H2 is the broad-sense heritability, and VP is the total phenotypic variance.
In this case, we are given H2 = 0.8 and VP = 21.30.
Thus, VG = 0.8 * 21.30 = 17.04.
Therefore, the best choice is B.
