Best answer: What phenotype does a heterozygous individual have in codominance?

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 phenotype dominant or recessive will a heterozygous individual have?

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. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

What phenotype is shown in codominance?

Indeed, “codominance” is the specific term for a system in which an allele from each homozygote parent combines in the offspring, and the offspring simultaneously demonstrates both phenotypes. An example of codominance occurs in the human ABO blood group system.

Codominance.

What is an example of heterozygous?

Your genes are made of DNA. … 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.

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.

What is the difference between a homozygous individual and a heterozygous individual?

A heterozygous individual is someone who has two different alleles at a locus. For instance, using the sickle cell example, a heterozygous individual might have a genotype of AS. A homozygous individual has two identical alleles at a locus. The genotype for a homozygous individual might be AA or SS.

How is incomplete dominance expressed in a phenotype?

How is incomplete dominance expressed in a phenotype? Neither gene is fully expressed, but they are mixed together. Looks different than both parents, introduces new “item.” Why might polygenic traits vary more in phenotype than do single-gene traits?

What is phenotype example?

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.

What traits are dominant and recessive?

Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.

What are two examples of codominance from the reading?

Examples of Codominance:

  • AB Blood Type. People with this blood type have A and B proteins at the same time. …
  • Sickle-Cell Anemia. Sickle cell anemia is a disease where red blood cells become thin and stretched out. …
  • Horse color. The roan coat color of a horse is due to codominance. …
  • Flower colors.
