Question: What represents a homozygous condition?

Homozygous refers to the state or condition that occurs when an individual inherits the same DNA sequence for a certain gene from both biological parents. … A homozygous trait is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.

What is an example of homozygous condition?

Homozygous examples

You can have brown eyes whether you’re homozygous (two alleles for brown eyes) or heterozygous (one for brown and one for blue). This is unlike the allele for blue eyes, which is recessive. You need two identical blue eye alleles in order to have blue eyes.

What is a homozygous condition?

​Homozygous

Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.

What represents a heterozygous condition?

​Heterozygous

= 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.

Which of these represents a homozygous genotype?

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. If that have Aa, they are heterozyous.

What do you mean by H * * * * * * * * * and heterozygous?

Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.

What represents homozygous and heterozygous allele?

An organism that is homozygous has two copies of the same allele. An allele is one version, like a “flavor”, of a gene. … Homozygous means having two of the same allele. Heterozygous means having two different alleles.

What represents a heterozygous genotype?

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 is heterozygous example?

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. The relationship between the two alleles affects which traits are expressed.

How do you differentiate homozygous and heterozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.

Is BB heterozygous or homozygous?

A bull with two alleles for a black coat is homozygous (BB). A calf that has one allele for red coat color and one allele for black coat color is heterozygous (Bb). Heterozygous individuals contain two different alleles which results in conflicting instructions.
