QUESTION 5 2 points Save Answer A biologist observes a population of horned beetles. Males have ornamental horns, and females prefer mates with longer horns. In one generation, males have a mean horn length of 3 cm, but the males who find mates and father offspring have a mean horn length of 5 cm. In the next generation, the sons of those males have a mean horn length of 3 cm, as shown in the figure below. What is the approximate heritability (h2) of male horn length and why? generation 1 all males generation 1 fathers 0 2 3 4 5 6 Horn length generation 2 all males 2 3 4 5 6 Horn length O The h2 is approximately 0.6 because the next generation's mean horn length is 3/5 of the fathers' mean horn length. O The h2 is approximately 1.0 because the next generation has the same mean as the previous generation. The h2 is approximately 0 because there is no response to the selection differential of 2 cm The h2 is approximately 2.0 because the difference between the mean horn length before and after selection is 2 cm. O There is not enough information to calculate the h2 of male horn length
