You asked: Is homozygous a phenotype?

A homozygous phenotype is the product of two identical genes.

Is homozygous a genotype or phenotype?

Recessive alleles only express their phenotype if an organism carries two identical copies of the recessive allele, meaning it is homozygous for the recessive allele. This means that the genotype of an organism with a dominant phenotype may be either homozygous or heterozygous for the dominant allele.

Is heterozygous a phenotype?

Heterozygous individuals have a phenotype somewhere in the middle, what people might call “wavy” hair. In a heterozygous individual, only one curly allele is present, and only half the amount of protein can be made.

Is homozygous an example of a phenotype?

While carriers have the dominant/recessive genotype for a given gene, they only show the phenotype caused by the dominant version of that gene. … For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white).

What does it mean when a genotype is homozygous?

(HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

Is AA heterozygous or homozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

Is homozygous dominant?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

What is an example of phenotype?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
