In a diploid organism, there are ___ number of copies of most genes. In a population, there may be many different gene sequences
sineoko [7]

Answer:

In a diploid organism there are two copies of most genes.

The versions of the genes are called alleles.

Explanation:

Hello!

The genetic servants of a population are all variants of each of the genes present. These variables are possible thanks to the mutations that occur in the formation of the zygote (before or after fertilization).

When part of the DNA of an organism undergoes a point mutation (on one or a few nitrogenous bases) the body activates a series of responses to reverse it, however sometimes the mutation is maintained and can give rise to a change in a protein.

Sometimes and under certain circumstances (the change should not cause death or significant disadvantages in the body that is born) the mutation is maintained in the population giving rise to different alleles of the same gene.

In an organism there are two copies of each gene (genotype) but only one of them (phenotype) is expressed.

The allele of the gene that is expressed may depend on various factors but the dominant allele is usually expressed.
