Answer:

b. form of a gene

Explanation:

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.

Humans, like all mammals, are diploid organisms. This means that we have two copies of each chromosome. In diploid organisms, one somatic cell would have two copies of each gene. This means that in one somatic cell, an individual carries two copies of alleles for long eyelashes, and also two copies of alleles for short eyelashes.

Setler79 [48]

Answer:

prophase
