What does heterozygous for color mean?

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. It also determines what characteristics you’re a carrier for.

What does it mean to be heterozygous for a gene?

Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

Is brown hair heterozygous or homozygous?

Brown hair is heterozygous. Blonde hair is homozygous recessive. This is an example of incomplete dominance.

What is the most dominant horse color?

Champagne, Dun, and Silver are all dominant traits, and therefore only one copy of dilution causing allele is needed to produce the respective phenotypes. Silver is interesting because it primarily affects black pigment of the points (black and bay horses).

Is BB homozygous or heterozygous?

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. In our example, this genotype is written Bb.

What is the genotype for heterozygous brown hair?

B, for brown hair, is a dominant allele. This means than someone who has a genotype of “BB” or “Bb” will have brown hair. In other words, that person’s phenotype will be that they have brown hair. Recessive alleles are represented with lowercase letters.
