Question

If the frequency of the A3 allele of a creatine phosphatase locus in a population of lions is 0.4, how many copies of that allele should we expect to see in a population of 500 lions?

Answer 1

We should expect to see 400 copies of A3 allele

Step-by-step explanation:

The frecuency (F) of an allele is equal to:

`F_(A3) =(Number of copies of allele)/(Total number of copies of gene in population)`

Given that lions are diploid organisms, which means they have two copies of each chromosome, there are in total 1000 copies of the creatine phosphatase locus (500*2=1000).

By replacing in the formula, be obtain that:

`0.4=(number of copies of allele A3)/(1000)`

`0.4*1000=number of copies of allele A3\\400- number of copies of allele A3`
