In southwest Arizona there is a large, isolated population of kangaroo rats with over 1000 individuals and a 50:50 sex ratio. You genotype these kangaroo rats at 10 SNPs. You start this genotyping project in the year 2020. In year 2050, the population undergoes a large population decline to 10 individuals and stays around 10 individuals until the year 2100, at which point you retire (at a very old age). Draw a plot illustrating the allele frequencies of all 10 loci from year 2020 to year 2100. Label all axes clearly! Now draw a second plot similar to that in the question above, except that in the year 2050 the population does not decline, but instead responds to a new selective pressure in the form of a novel disease spreading into the population. The disease is a strong agent of selection and results in considerable mortality. Importantly, 5 of the loci are neutral and the other 5 are linked to genes that play a role in disease resistance. Explain your plots. I need an appropriate answer for this question.
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.
