Question: What do you call an individual that is heterozygous at two genes?

heterozygous. a genotype consisting of two different alleles of a gene for a particular trait (Aa). Individuals who are heterozygous for a trait are referred to as heterozygotes.

What does it mean when two genes are 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.

What is an individual heterozygous for both traits?

When you’re heterozygous for a specific gene, it means you have two different versions of that gene. The dominant form can completely mask the recessive one, or they can blend together. In some cases, both versions appear at the same time. The two different genes can interact in various ways.

What if an individual were heterozygous?

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 does it mean for 2 genes to be homozygous?

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 term heterozygous mean?

(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 do you call homozygous and heterozygous?

An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait. In plant and animal breeding, such organisms can be called homozygotes and heterozygotes.

What is an individual with two recessive alleles for the same trait called?

Individuals with two of the same alleles for a trait are said to be homozygous for that trait.

What is a cross of two individuals for a single contrasting trait called?

A cross of two individuals for a single contrasting trait is called. monohybrid. If an individual possesses different alleles for a character , the individual is said to be. Heterozygous for the trait .

Which term applies to an individual who possesses two recessive alleles?

If the individual has two recessive alleles for the same trait, the individual is said to be… Homozygous for the trait. An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produced many offspring.

What is it called when two genes are in a cell and one gene’s phenotype is expressed and one is not?


= Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

How will you describe the heterozygous individual in incomplete dominance?

In incomplete dominance, the phenotype in a heterozygous individual is visibly less intense than that in an individual homozygous for the dominant allele, so that AA and Aa genotypes produce different phenotypes. Hence, the heterozygote (Aa) will have a phenotype intermediate between that of AA and aa individuals.

Have gene pairs with genes that are?

Purebred – Also called HOMOZYGOUS and consists of gene pairs with genes that are the SAME. Hybrid – Also called HETEROZYGOUS and consists of gene pairs that are DIFFERENT. Genotype is the actual GENE makeup represented by LETTERS.

What is homozygote and heterozygote?

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.

How are homozygous and heterozygous similar?

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.
