A trait with only two forms in the population, wild type and mutant, would exhibit which one of the following types of genetic variation in the population? Continuous Discontinuous Both continuous and discontinuous Neither continuous nor discontinuous
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.

-
- Continuous
- Discontinuous
- Both continuous and discontinuous
- Neither continuous nor discontinuous
Natural selection works on the phenotype, or observable characteristics, of an individual. The phenotype is also essentially a genotype result (the alleles, or gene versions, the organism carries).When a phenotype produced by certain alleles allows species to survive and replicate better than their peers, the frequency of the helpful alleles can be increased from one generation to the next by natural selection, i.e. it can cause microevolution.
