Therefore, the parent with purple flowers must have the genotype Bb .
What is the genotype of a blue person?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb . Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
What phenotype is AA?
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.
Is purple a genotype or phenotype?
The trait that is shown due to the coding in the genotype is called the phenotype . The phenotype is the actual physical features shown by the organism. In pea plants, like in the example above, if the dominant allele for purple flowers is present in the genotype, then the phenotype would be purple.
What color is a genotype?
An organism’s genotype is its specific combination of alleles for a given gene . So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
Can AA genotype marry AA?
Compatible genotypes for marriage are:
AA marries an AA. That’s the best compatible. That way you save your future children the worry about genotype compatibility. ... And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
What are the 4 phenotypes?
| Phenotype Possible Genotype | A AA or AO | B BB or BO | AB AB | O OO |

What is blue skin?
A bluish color to the skin or mucous membrane is usually due to a lack of oxygen in the blood. The medical term is cyanosis .
Are green eyes recessive?
Alleles are alternative forms of a gene that, in this case, are responsible for giving your baby a certain eye color. The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive .
Are blue eyes homozygous or heterozygous?
People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene . The recessive allele is expressed because there isn’t a dominant one to mask it.
Which flower color is dominant purple or white?
| Trait Dominant Expression Recessive Expression | Color of flower (P) Purple White | Form of ripe pods (I) Inflated Constricted | Color of unripe pods (G) Green Yellow | Position of flowers (A) Axial Terminal |
|---|
Is PP purple or white?
the allele P (purple) is dominant . this means that if there are one or more alleles present in the genotype of the offspring (Pp or PP), the flower will be purple. the flower can only be white if there are two recessive genes – if the flower were white, the genotype would have to be pp.
What is 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.
Which genotype has the strongest immune system?
The GG genotype of SP induced stronger immune responses than those of the other two genotypes in the pattern recognition molecule and immune-responsive effector pathways.
What does genotype AA mean?
The term “ homozygous ” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
What is the blood group of AA genotype?
| Mother’s Blood Type Possible Mother’s Genotype Possible Father’s Genotype | A AA, AO AA, AO | A AA, AO AB | A AA, AO BB, BO | A AA, AO OO |
