A pea plant that has two different alleles for the same trait is said to be..

|
polygenic
|
|
|
heterozygous
|
|
|
homozygous
|

|
heptazygous

Explanation:
Detailed explanation-1: -Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white).
Detailed explanation-2: -If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
Detailed explanation-3: -An organism with two identical alleles is homozygous.
