Your question: Is MM homozygous dominant?

Is MM homozygous dominant or recessive?

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. 13) In this list of genotypes, which ones are examples of HETEROZYGOUS genotypes?

What would be a homozygous dominant?

Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.

Is CC homozygous recessive?

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

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.

Is EE dominant or recessive?

For example, the heterozygous genotype for earlobe type (Ee) produces detached earlobes because the dominant allele (E) hides the effects of the recessive allele (e). The homozygous dominant genotype (EE) also produces detached earlobes, so detached earlobes are considered the dominant trait.

Is AA homozygous dominant?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

How do you know if a dominant trait is homozygous or heterozygous?

To identify whether an organism exhibiting a dominant trait is homozygous or heterozygous for a specific allele, a scientist can perform a test cross. The organism in question is crossed with an organism that is homozygous for the recessive trait, and the offspring of the test cross are examined.

Is homozygous dominant a phenotype?

A homozygous dominant allele combination contains two dominant alleles and expresses the dominant phenotype (expressed physical trait). A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype.

Does heterozygous mean dominant?

Difference between homozygous and heterozygous

Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed.

Is P or Q recessive?

In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and q for the frequency of the recessive allele.
