What is the genotype for GG?
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.
What is an example of a heterozygous genotype?
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.
Is GG an example of a genotype?
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).
How do you know if a genotype is heterozygous?
For every gene, you inherit two alleles: one from your biological father and one from your biological mother. Together, these alleles are called a genotype. If the two versions are different, you have a heterozygous genotype for that gene.
Is GG green or yellow?
One can use the letters capital G to represent the dominant color green, and lower case g, to represent the recessive trait yellow. Therefore, if an offspring’s genotype is GG, then it is said to be homozygous green.
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|
Which is heterozygous AA AA or AA?
Homozygous means that both copies of a gene or locus match while heterozygous means that the copies do not match. Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
Is AA heterozygous or homozygous?
If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.
What does a GG allele mean?
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. … An organism’s genotype results in an organism’s phenotype.
