A gene can have many alleles. Why is it that any given person only carries two copies of each allele

1 answer:

3 0

Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.
