Now, a pea with t he genes GG will be green is color, gg is yellow, and Gg is green due to the dominant gene, G. The GG, Gg, and gg above are known as genotypes. They denote the specific genes for that trait.
Is the genotype GG heterozygous or homozygous?
Remember that the genotype is the combination of the alleles and the phenotype is the actual physical trait that is expressed. Example: A homozygous green pea plant (GG) is crossed with a heterozygous green pea plant (Gg).
What does G G genotype mean?
For example, someone with a “GG” genotype has a 97 percent chance of having light eyes. … Many other factors influence eye color, including your ancestry, other genes, and other non-genetic factors.
What is the phenotype of a plant with the genotype GG?
For example, the GG parent and the Gg offspring have the same phenotype (green pods) but different genotypes. An organism’s genotype results in an organism’s phenotype.
Is GG purebred?
Read the chart to answer the question.
Reading Punnett Squares and Pedigree Charts.
|What is the probability of having purebred offspring from this cross?,||50% – GG is purebred|
|What is the probability of having a homozygous green pea from this cross?,||50% – GG is homozygous green|
Is AA a genotype?
What is a Genotype? … There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
Is AA homozygous or heterozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
What is GG eye color?
Individuals with the genotype rs12913832:GA, who are expected to have brown eye colours, may have blue eye colours, and individuals with the genotype rs12913832:GG, who are expected to have blue eye colours, may have brown eye colours [10, 11].
Why do genotypes have 2 letters?
The two letters in a genotype represent the pair of alleles. The uppercase letter represents the dominant allele and the lowercase letter represents recessive allele.
