A hypothetical study investigated the vitamin A content and the cholesterol content of eggs from a large population of chickens. The variances ( V ) were calculated, as shown here: 11eb563d_4e65_5674_a8c8_0721824c4269_SM1220_00 (a) Calculate the narrow-sense heritability ( h 2 ) for both traits. (b) Which trait, if either, is likely to respond to selection?
