Let us say that gene flow among the islands is uniform over the interval of study but varies across islands. Also, the islands have effective population sizes as indicated in the table, except you must enter your estimate for Ne for island A from problem 8. Ne m Island A ________ 0.59 Island B 112.6 0.46 Island C 517.9 0.02 9) Which island, based strictly on Ne, is most likely to experience fluctuations in allele frequencies due to random genetic drift? (A) island A (B) island B (C) island C 10) Which island, based on the combined evidence of Ne and
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.
