Question

Pea seed color exists as green or yellow. We might say that "yellow" is an example of a (an)_ for seed color

Answer 1

Answer:

b. allele

Explanation:

An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).

The other options are wrong because:

The genotype is the combination of alleles an individual has.

The karyotype is an individual's collection of chromosomes, paired and ordered.

A homozygote individual has the same alleles for a particular gene.

A heterozygote individual has different alleles for a particular gene.
