Lelechka [254]

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).

<h3>What is ATP?</h3>

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is  usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.
