Concept explainers

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.

Steven Frank and Laurence Hurst argued that a cytoplasmically inherited mutation in humans that has severe effects in males but no effect in females will not be eliminated from a population by natural selection because only females pass on mtDNA. Using this argument, explain why males with Leber hereditary optic neuropathy are more severely affected than females.

Crickets have colonized each island in the Hawaiian Archipelago. Geological data indicates that Kauai is the oldest island in the chain and Hawaii is the youngest. Researchers hypothesized that crickets sequentially colonized islands as they rose out of the ocean and created a cladogram based on molecular relationships to test this idea. 3) Which islands unambiguously show multiple independent colonization events? 4) How many colonization events were there on each of the islands showing multiple events?
