Height is a trait that shows continuous variation in humans. In pea plants, onn the other hand, the tall allele is dominant over the short allele and there are no intermediate heights. What is the best explanation for this differencea. the alleles that control height in pea plants are epistaticb. the alleles that control height in pea plants are pleiotropicc. the alleles that control height in humans are pleiotropicd. height is a polygenic trait in humanse. height is a polygenic trait in pea plants

height is a polygenic trait in humans

Explanation:

Height in pea plant is controlled by two alleles of a single gene. So, height in pea plant exhibits discontinuous variations and is present in distinct phenotypic categories (tall or short). On the other hand, height in humans is controlled by more than one gene. This trait is polygenic. The phenotype of an individual depends on sum total of dominant alleles of all the genes that control height. Therefore, height in humans exhibits continuous variations.

the binding of the substrate is dictated by the shape of each molecule. side chains on the enzyme interact with the substrate in a specific way, resulting in the making and breaking of bonds.
