A conservation biologist studied four generations of a population of rare Ethiopian jackals. When the study began, there were 47 jackals in the population, and microsatellite analysis showed a heterozygosity of 0.55. In the second generation, an outbreak of distemper occurred in the population, and only 17 animals survived to adulthood. These jackals produced 20 surviving offspring, which in turn gave rise to 35 progeny in the fourth generation. a) What was the effective population size for the four generations of this study? b) Based on its effective population size (use the rounded off value you obtained in a), what is the heterozygosity of the jackal population in generation 4 (t=4)? c) What is the inbreeding coefficient in generation 4, assuming an inbreeding coefficient of F = O at the beginning of the study (t=1), no change in microsatellite allele frequencies in the gene pool, and random mating in all 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.
