What do heterozygous and homozygous mean?

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 heterozygous and homozygous examples?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

What's the difference between homozygous and heterozygous?

We all have two alleles, or versions, of each gene. Being homozygous for a particular gene means you inherited two identical versions. It's the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.

What's an example of 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 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 meant by homozygote?

homozygote, an organism with identical pairs of genes (or alleles) for a specific trait. If both of the two gametes (sex cells) that fuse during fertilization carry the same form of the gene for a specific trait, the organism is said to be homozygous for that trait.

Are males heterozygous?

Rather than homozygous or heterozygous, males are said to be hemizygous for X-linked genes.

What happens when both parents are heterozygous?

If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow's peak (see figure). A Punnett square can be used to determine all possible genotypic combinations in the parents.

How do you tell if a parent is homozygous or heterozygous?

If the test cross results in any recessive offspring, then the parent organism is heterozygous for the allele in question. If the test cross results in only phenotypically dominant offspring, then the parent organism is homozygous dominant for the allele in question.

What is the purpose of a Punnett square?

A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

What does homozygous dominant mean?

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.

What is homozygous psychology?

adj. possessing identical forms of a gene (i.e., identical alleles) at a given genetic locus on each of a pair of homologous chromosomes.

Which trait is homozygous dominant?

A homozygous dominant genotype is one in which both alleles are dominant. 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's another term for homozygous?

Find another word for homozygous. In this page you can discover 11 synonyms, antonyms, idiomatic expressions, and related words for homozygous, like: homozygote, heterozygous, heterozygote, C282Y, homozygosity, wild-type, genotype, recessive, diploid, allele and MC1R.

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.
