You are a biologist interested in the variation in the body size of Florida sea turtles. You krnow that body size is determined by a single locus. with two alleles, with large body size (A) dominant over small bOdy size (a) survey the body size of 100 turtles and observed the following phenotype frequencies: Large bodied turtles (AM and Aa) - 84 Small bodied turtles (aa) - 16 If the population is in HWE, how many turtles of each genotype would you expect? O AA - 84, Aa - 0, and aa = 16 O AA - 36, Aa- 48, and aa = 16 O AA - 42, Aa - 42, and aa - 16 O AA - 24, Aa - 60, and aa - 16 O AA - 16, Aa - 68, and aa 16

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.
