Answer:
0,58
Explanation:
Mice are diploid (2n) organisms, which means that their cells contain two complete sets of homo-logous chromosomes (i.e., they have two copies of any given <em>locus</em>/gene). An allele can be defined as a variant of a gene, whereas diploid (2n) organisms have two alleles at each genetic <em>locus</em>, which are located on homo-logous chromosomes. In this case, we know that there are 580 dominant alleles in a population of 500 individuals, thereby the total number of alleles in this population is 1000 (2n >> 500 x 2 = 1000 alleles), and the frequency of the dominant allele is 0,58 (580/1000 = 0,58).
