How are alleles for the same gene related? A. They have different genetic sequences but are found in the same location on a chro
Dmitrij [34]

Answer:

A. They have different genetic sequences but are found in the same location on a chromosome.

Explanation:

In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.

Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
