You asked: Is CC homozygous or heterozygous?

Is CC homozygous recessive?

All of the above results have involved comparisons of the heterozygote (Cc) with the homozygous recessive genotype (cc).

Is KK homozygous or heterozygous?

The testcross is another procedure to identify the genotype of a plant. In the testcross the plant in question is crossed with a plant homozygous and recessive for the trait being observed. In the F2 above, hooded plants were either homozygous (KK) or heterozygous (Kk).

What is a homozygous recessive?

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. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

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).

What is 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.

Is JJ homozygous dominant?

Hint: Bb, Hh, Zz, and Jj are all examples of hybrid genotypes. … Homozygous genotypes have either all dominant alleles (all capital letters) or all recessive alleles (all lowercase letters). TT, YY, PP, MM, QQ, qq, mm, tt.

Is JJ dominant or recessive?

Another gentleman does not possess this gene – instead, he has the recessive jj gene which means his joints bend normally. A boy is born with an extra finger on each hand due to the dominant gene EE, while another newborn with the recessive homozygous ee gene has the normal number of fingers on her hands.

Is GG homozygous or heterozygous?

The true-breeding parents GG and gg are homozygous for the pod color gene. Organisms that have two different alleles for a gene are called heterozygous (Gg). The offspring of the cross between the GG (homozygous dominant) and gg (homozygous recessive) plants are all heterozygous for the pod color gene.
