Smooth seed shape is dominant to wrinkled. F2 generation is as follows: 3/4 smooth : 1/4 wrinkled. What were the phenotypes of the P1 parents? A) SS×ss B) Smooth and wrinkled C) Ss× Ss D) smooth × smooth E) Ss ×ss
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

Gregor Mendel experimented on garden pea.This was because peas possesses four important qualities:
- Peas had been shown to be true-breeding
- Peas exhibit a variety of contrasting traits.
- Pea plants grow quickly and do not require much space
- The shape of the pea flower protected it from foreign pollen.
Among the seven contrasting traits shape of the pea was one of them.The pea shape were two types round or wrinkled.Round seed shape is dominant over wrinkled seed shape.
