Answer:
600
Explanation:
A since locus, we have two copies of alleles. Refering bak to the question, if we multiply two (2) copies of alleles in a single locus by the given three hundred (300), this will give us six hundred (600) which happens to be the answer and the number of copies of alleles in three hundred locus.
Also for the purpose of clarity, we need to define some terms:
Alleles: This is a specific type of gene reflecting to the representation of two or more versions of a known mutation at the same place on a chromosome. It also indicates to different array of several-hundred base-pair or more region of the genome that codes for a protein.
