Effect of geographic distance from Africa on human genetic diversity - Why do humans have a low genetic diversity compared to great apes? Founder effect… - Why is the concept of race NOT supported by science? (4 reasons) - Know that skin color varies within/between populations in a way that suggests stabilizing natural selection - Why is skin color adaptive? - Know the differences between genetic and cultural evolution - Why do different groups tend to have different cultures?
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.
Genetic Diversity is the diversity of genetic characteristics expressed or recessive within a species i.e. between individuals and populations of the same species.
