Height in humans depends on the additive action of genes. Assume that this trait is controlled by the four loci R, S, T, and U and that environmental effects are negligible. Instead of additive versus nonadditive alleles, assume that additive and partially additive alleles exist. Additive alleles contribute two units, and partially additive alleles contribute one unit to height. Can two individuals of moderate height produce offspring that are much taller or shorter than either parent? If so, how?

Hello everyone and welcome to today's video. So green color in wheat depends upon the additive action of two genes identified the ratio of the F two generation. When we with red grain was crossed with wheat with white grain, we'll remember that when we're crossing these wheat that has red grain and wheat that has white grain. The F one generation is going to be an intermediate color between all of them and that is the only color that is going to be present in the F one generation, so it has a ratio of one. However, if we inter mate these F one generation that is just full of intermediate colors, we're going to get a ratio that looks like this and this is going to be represented by answer choice. I really hope this video helped you and I hope to see you on the next one.
