What do we call an organism that is homozygous for a trait?

What is an organism that is heterozygous for a trait?

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). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

What do we call a trait that shows in a heterozygous individual?

In a codominant trait, the heterozygous individuals will show the phenotype of one allele on some parts of their body, and the phenotype for the other allele in different parts of the body.

What is an example of a homozygous organism?

If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous. Keep in mind that an organism can’t simply be ‘homozygous,’ period.
