What is the phenotype of a heterozygous genotype?

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. … Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.

What is a heterozygous genotype allele?

Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What is it called when both alleles show up in the phenotype?

Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. … In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.

When the genotype consists of a dominant and a recessive allele the phenotype will be allele?

When there is a genotype that consists of a dominant and a recessive allele, the phenotype generally looks like the dominant one.

Which term describes an organism with two of the same alleles for a particular trait?

If an organism contains two identical alleles for a particular trait, the genotype for this trait is said to be homozygous.

How do you determine heterozygous phenotype?

An organism’s genetic makeup is called its genotype, and it reflects all of the alleles, or forms of the gene, that are carried by the organism. Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

What is the phenotype of a homozygous recessive?

The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive ( tt ) ( Figure below ).

Genotype Definition Example
Homozygous recessive Two recessive alleles tt

Is AA heterozygous or homozygous?

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.

Which is a heterozygous genotype *?

A heterozygous genotype is a genotype that has multiple different alleles present in that gene. For example, a genotype that is “Tt” would be heterozygous, where the capital “T” could represent the trait of “tall” and the lowercase “t” could represent the trait of short.
