The diagram shows a plant that is heterozygous for two genes. G = yellow; g = green; R = round; r= wrinkled G Four different types of gametes are produced by a heterozygous individual when crossing over occurs, and two different types of gametes are produced when crossing over does not occur. What does this information reveal about crossng over? O Crossing over introduces variety by producing different combinations of alleles. O Crossing over reduces the incidence of DNA and chromosomal mutations. O Crossing over introduces variety in nature by creating new types of genes. O Crossing over maintains the count of genes and the original alleles in both chromosomes.

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.
