How did mendel change the world?

Answer 1

While he crossed 2 pea plants (1 yellow/round-dominant, 1 green/wrinkled-recessive; both plants are heterozygous), he saw that 9 of the offspring were yellow and round, 3 of them were green and round, 3 were yellow and wrinkled, and 1 was green and wrinkled. As shown, this is a dihybrid problem (16 squares). Monohybrid problems are very simple.

There is also incomplete dominance where a red flower and a white flower cross and produce pink flowers; this means that the offspring did not have the alleles from the parents, so the traits blended. Another type would be co-dominance where the offspring share the alleles of both parents; an example would be the roan cattle (it has both red and white colors from its parents). Multiple alleles are usually in blood types (type A, B, O). Blood type AB is co-dominant.

Today, scientists recognize Mendel's discovery of genetics; therefore, it is important people should study genetics in Biology.
