You are studying a large flock of chickens and divide it into two halves. Each half contains the same genetic variations at the same frequencies as in the other half. To one half (the control group) you feed normal chicken chow, to the other half (the experimental group) you feed normal chicken chow supplemented with a nutritional booster. As expected, in the experimental group the hens lay an average number of eggs greater than those in the control group. Yet the heritability remains the same in both the experimental and control groups. You can explain this observation by hypothesizing that the variation in nutrition among hens is, select one of the options below and justify your answer.

A. smaller in the experimental group.

B. larger in the experimental group.

C. the same in both groups.

D. smaller in the control group.

E. larger in the control group.

What is the difference between self-pollination and cross-pollination? question 2 options: self-pollination leads to the creation of a fruit. cross-pollination does not. during cross-pollination, ovules are carried from one plant to another plant.. during self-pollination the ovules stay on the same plant. during cross-pollination, ovules are carried from one plant to another plant.. during self-pollination the ovules stay on the same plant. during cross-pollination the pollen grains are carried from one plant to another plant. during self-pollination the pollen and ovules are from the same plant. during cross-pollination, the pollen grains travel from the stigma to the anthers. during self-pollination, the pollen grains travel from the anthers to the stigma.
