These sex-linked loci have different doses of loci in males and females and have Hardy--Weinberg equilibria that differ from those for non sex-linked (autosomal loci) loci. The relationship between allele and genotype frequencies according to the Hardy--Weinberg equilibrium is shown in Fig. 1. This illustrates two points. 5 (50%) for a locus with two alleles. 5. Second, when an allele is rare, most of its alleles are in heterozygotes, while most are in homozygotes when it is at a high frequency.

00 (‘immigrants’) All the non-J alleles in the Web Valley population have come from dogs. 0 Thus, the Web Valley population of Ethiopian wolves derives about 22% of its genetic composition from domestic dogs. This is the accumulated contribution of alleles from dogs, not a per-generation estimate. Phenotypically abnormal individuals, suspected of being hybrid individuals, represent about 17% of the population. Estimates can also be made from other microsatellite loci and the best estimate would come from combining information from all relevant loci.

American alligator Royal mahogany 29 30 GENETIC DIVERSITY the most likely explanation is that threatened species have suffered reductions in population size that directly result in loss of genetic diversity. What components of genetic diversity determine the ability to evolve? Quantitative genetic variation for life history traits is the major determinant of evolutionary potential. Unfortunately, we have least information on this form of genetic diversity and it is the most difficult to measure Evolutionary potential is most directly measured by estimating the quantitative genetic variation for reproductive fitness.
