What is the definition of heterozygous and homozygous?

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.

What is a simple definition of homozygous?

The term homozygous is used to describe that which has the same or identical alleles for a particular trait located at similar loci on paired chromosomes (i.e. homologous chromosomes). In a diploid organism, there are two sets of chromosomes. ... It means that the alleles code for the same trait.

What is the best definition of homozygous?

Definition of homozygous

: having the two genes at corresponding loci on homologous chromosomes identical for one or more loci.

What do you mean by heterozygous?

(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 an example of a heterozygous?

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.

What is homozygous example?

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.

What is the difference between heterozygous and heterozygote?

Heterozygous. A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene. The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype.

What is a homozygous trait?

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

What is an example of homozygous genotype?

A homozygous genotype is one in which both alleles are the same, and an organism with a homozygous genotype is said to be true-breeding or purebred. ... For example, in pea plants, height is governed by a single gene with two alleles, in which the tall allele (T) is dominant and the short allele (t) is recessive.

What is homozygous short answer?

(HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

What is the difference between hemizygous and homozygous?

The key difference between homozygous and hemizygous is that homozygous is the condition in which both alleles of a diploid organism are the same while hemizygous is the condition in which only one allele is present. ... Hemizygous is that state of having only one copy or allele of a gene.

What is the difference between heterozygous and homozygous set of alleles?

Distinguish Between Homozygous and Heterozygous

The terms Homozygous and Heterozygous are used to describe allele pairs. A Homozygous individual carries a set of two identical (RR or rr) alleles while a Heterozygous individual bears different alleles (Rr).

Which is a phenotype?

A phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

What is the phenotype of a heterozygote?

Heterozygous individuals have a phenotype somewhere in the middle, what people might call “wavy” hair. In a heterozygous individual, only one curly allele is present, and only half the amount of protein can be made. This causes the hair to be about as half as curly as in a homozygous curly individual.

What are alleles in biology?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. ... Alleles contribute to the organism's phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.
