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 is the phenotype of a plant with the genotype GG?
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 the genotype GG 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.
What is the ratio for genotype GG?
As you can see, 1/2 of the offspring are genotype Gg and 1/2 are gg.
What is genotype and phenotype in pea plant?
An organism’s genotype is its specific combination of alleles for a given gene. ... The phenotype is the physical manifestation of an organism’s allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible.
Is AA a genotype or phenotype?
| Phenotype Possible Genotype | A AA or AO | B BB or BO | AB AB | O OO |

Is TT a genotype or phenotype?
| Genotype Symbol Genotype Vocab Phenotype | TT homozygous DOMINANT or pure tall tall | Tt heterozygous or hybrid tall | tt homozygous RECESSIVE or pure short short |

What does AA genotype means?
A homozygous dominant (AA) individual has a normal phenotype and no risk of abnormal offspring. A homozygous recessive individual has an abnormal phenotype and is guaranteed to pass the abnormal gene onto offspring.
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.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous .
Is there a 4 0 phenotypic ratio?
As there is no second phenotype, there is no phenotypic ratio . If we did put this result as a ratio, it would be 4:0. ... The genotypic ratio is, therefore, 0:4:0.
What is the difference between genotype and phenotype?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not . Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
What is an example of a phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. ... Examples of phenotypes include height, wing length, and hair color .
Is FF heterozygous or homozygous?
| Genotype Phenotype | F F Homozygous dominant No cystic fibrosis (Normal) | F f Heterozygous Carrier (has no symptoms but carries the recessive allele) | f f Homozygous recessive Cystic fibrosis (has symptoms) |
