What is the genotype called when there are two of the same alleles?

What is the genotype of two of the same allele?

A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.

What is it called when two alleles are the same?

If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.

What is it called when alleles A and B are in the same genotype?

Codominance

= Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent.

What is BB genotype?

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 a genotype and phenotype?

The genotype refers to the genetic material passed between generations, and the phenotype is observable characteristics or traits of an organism.

What are the heterozygous genotypes?

(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 are the 3 types of genotypes?

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

What represents homozygous genotypes?

A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous.

What is my genotype?

In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
