3. | In an experimental population of Tribolium (flour beetles), the body length shows a continuous distribution with a mean of 6 mm. A group of males and females with body lengths of 9 mm are removed and interbred. The body lengths of their offspring average 7.2 mm. From these data, calculate the heritability in the narrow sense for body length in this population. See answer

| Solution The selection differential is 9 6 = 3 and the selection response is 7.2 6 = 1.2 Therefore, the heritability in the narrow sense is See question
