Medel obtained the following types of seeds after self-pollination in pea plants with round, yellow seeds.

Examine the outcome and explain the inheritance mechanism that produced it.

The obtained ratio is 9: 3: 3: 1, in which both parental and new combinations are seen. This shows that the genes of the progeny plants were not entirely inherited from each parent. From the pair of maternal and paternal chromosomes, each germ cell takes one chromosome. One pair of characters can separate from another pair of characters independently when two germ cells join.
