Homework Answers
autozygous refers to identical alleles (AA or aa) of a gene often results from practice of inbreeding or non-random mating due to small populaion size.
Small population size leads to a decline in heterozygosity due to allele fixation (where only one of the two allele of a gene gets selected and passed on to next generation). the choice of the allele being fixed in the population is very much random. This random change in allele frequency in a finite population is due to genetic drift.
So a population very strongly impacted by genetic drift is likely to display the highest degree of autozygosity.

One major concern in conservation biology is the loss of genetic variation in small populations due to genetic drift via bottlenecks. If a drastic bottleneck reduces the size of the population to 12 which had an initial heterozygosity of 0.38, How much of the initial heterozygosity will be lost after one generation? After the bottleneck If the population size remains the same in each following generation how much of the initial heterozygosity will remain after 10 generations?
