Question

alternate forms of the same gene are called
multiple choice
alleles.
crosses.
cofactors.

Explanation:

Alleles are different forms of a gene. For example, in pea plants, there is a gene for flower color, and the alleles could be for purple or white flowers. Crosses refer to the breeding of organisms (like a genetic cross between two plants). Cofactors are non - protein chemical compounds that assist in the function of proteins (like enzymes). Since the question is about alternate forms of a gene, alleles is the correct term.

Answer:

alleles.
