What is an example of a heterozygous allele pair?

Together, these alleles are called a genotype. 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.

What allele pair is heterozygous?

When the two alleles are not identical, the pair is heterozygous. In contrast, an identical pair is homozygous. The traits actually expressed by a heterozygous pair of alleles depend on the relationship between the two alleles and possibly the effects of other genes.

What is an example of a homozygous allele pair?

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.

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.

Which of the following 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 is heterozygous cross?

A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.

Is HH homozygous or heterozygous?

Half the possible offspring will be homozygous, HH, and half will be heterozygous, Hh.

Is EE heterozygous or homozygous?

The individual is homozygous for the trait when it has two identical alleles. In the example above about earlobes, both the EE and ee individuals are homozygous for the trait. The person with the Ee genotype is heterozygous for the trait, in this case, free earlobes.

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 is the genotype for black hair?

The genotype for black hair color is represented by the letter “B The genotype for blonde hair is represented by the letter “b.” You inherit two black alleles for hair color. You are considered for hair color: Homozygous recessive Homozygous dominant Hemizygous Heterozygous. Dennis H.

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 is heterozygous recessive example?

One such example is brown eyes (which is dominant) and blue eyes (which is recessive). If the alleles are heterozygous, the dominant allele would express itself over the recessive allele, resulting in brown eyes.

Which of the following is a heterozygous trait?

An organism that is heterozygous for a trait has two different alleles for that trait. … Flies that do not inherit the dominant allele have wrinkled wings. Flies that are heterozygous for the trait, having one dominant and one recessive allele, exhibit normal wings.
