Mendel noted in his experiments with pea plants that certain traits disappeared in the F1 generation, only to reappear in the F2 generation. Which of the following statements correctly describes the reason for this? O The mechanisms controlling the appearance of traits in the F1 and F2 plants were different. O Members of the F1 generation had only one allele for each trait, but members of the F2 generation had two alleles for each trait. O New mutations were frequently generated in the cross that generated the F2 generation. O Traits can be dominant or recessive, and the recessive traits are "hidden" by the dominant ones in the F1 generation.

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.
