WebbEach of the parent plants would have three alleles that made pigment, leading to pinkish kernels. Their offspring, however, would fall into seven color groups, ranging from no pigment whatsoever ( aabbcc) and white kernels to lots of pigment ( … Webb25 jan. 2024 · Polygenic Inheritance is produced by the cumulative effect of many genes. It is a form of non-Mendelian inheritance which deviates from the typical phenotypic Mendelian ratio. Polygenic Inheritance is found in both animals and plants. No two people can be exactly the same; even the twins have minute differences in them.

Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color. Rather, a genetic mutation causes a difference in fur color, which may help that rabbit hide better in its environment.

WebbDiscontinuous variation is the variation seen among individuals when each individual shows one of two—or a very few—easily distinguishable traits, such as violet or white flowers.
