What does heterozygous mean in simple terms?

What is heterozygous with examples?

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 the meaning of homozygous and heterozygous?

Heterozygous is when different forms of a specific gene are inherited from each parent. Homozygous is when a gene inherited from each parent is identical. Basically, heterozygous means different while homozygous means the same.

What is the definition of heterozygous trait?

By. Getty Images. Heterozygous is a term used in genetics to describe when two variations of a gene (known as alleles) are paired at the same location (locus) on a chromosome. By contrast, homozygous is when there are two copies of the same allele at the same locus.

What is homozygous in a sentence?

Homozygous sentence example

Whether the cat is heterozygous or homozygous for W, the blue eyes and deafness have incomplete penetrance. … Thalassemia major ( homozygous thalassemia or Cooley’s anemia) occurs in children in whom both parents pass on the genes responsible.

What is heterozygous and homozygous examples?

Homozygous means that the organism has two copies of the same allele for a gene. … 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).

Which of these is an example of 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.

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 is the difference between homozygote and heterozygote?

A heterozygote is an individual having two different alleles at a genetic locus; a homozygote is an individual having two copies of the same allele at a locus.
