A ship was caught in a storm and landed on a small island in the middle of the South Pacific. For generations, no one encountered this small colony who, despite the odds, made a thriving settlement on their island. After many years, what characteristics would be unique about this island population? a. The people would look very different from each other, and may have evolved some odd characteristics that aren't seen in other humans. b. The people would look very different from each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. c.The people would look very similar to each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. d. The people would no longer be considered humans after evolving independently for several generations.
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.

When two communities are divided by geographical boundaries like rivers, volcanoes, or bodies of water, they are said to be geographically isolated.
