Question

What are alleles?

a. Similar genes that are found in different species
b. Alternative versions of the same gene
c. Different genes that have similar functions

Answer 1

Alleles are alternative versions of the same gene that can result in variations of a trait or characteristic. A diploid organism can be homozygous or heterozygous for a gene.

Step-by-step explanation:

Alleles are alternative versions of the same gene. They are different forms of a gene that can result in variations of a trait or characteristic. A diploid organism can be homozygous, meaning it has two identical alleles for a gene, or heterozygous, meaning it has two different alleles for a gene.
