Your question: Which set of alleles are homozygous?

What alleles are homozygous?

Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

What is an example of homozygous allele?

Homozygous means that the organism has two copies of the same allele for 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.

Is CC a heterozygous or homozygous?

The observation that the agouti parent of unknown genotype can have an offspring with the albino phenotype (cc) means that the parent must be able to transmit the recessive c allele. Thus the parent is heterozygous (Cc) at the C locus.

What is a homozygous dominant set of alleles?

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.

Is TT a heterozygous?

If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero- means different).

Which is the best example for homozygous?

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 and BB homozygous?

A genotype such as either BB or bb the alleles are identical. An individual with this type of genotype is called homozygous. For a genotype such as Bb the alleles are different from one another. An individual with this type of pairing is called heterozygous.

Which of the following is homozygous dominant?

The correct answer: The genotype which shows the character of homozygous dominant is D. SS.
