What is a genotype example?
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).

What is the genotype of YY?
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles).
What are the 3 genotypes?
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp).
What is genotype AA?
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 meaning of AA AS and SS genotype?
Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA, AS, AC, SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.

What is the genotype AaBb?
A heterozygous for two genes AaBb has two types of alleles for each gene: A and a, B and b. The assortment of "A" and "a" into gametes is independent of the assortment of "B" and "b".
What genotype is FF?
Mendelian Genetics
| 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) |
What is AA AS and SS genotype?
Typically, there are five (5) distinct types of blood genotype. They are AA, AS, AC, SS, and SC. While the first 2 pairs (AA & AS) are normal, AC is rare and the latter two (SS, SC) are irregular and anomalous, commonly causing sickle cell disease.
What genotype is DD?
Background: The DD genotype gene is a linkage marker for an etiologic mutation at or near the angiotensin-converting enzyme gene and has been associated with increased risk for the development of coronary artery disease, left ventricular hypertrophy and left ventricular dilation after myocardial infarction.
What is HB genotype AA?
Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA, AS, AC, SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.
What is AA genotype?
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”.
Can O+ Be AA?
Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles….Blood types and genotypes?
| Blood type | Possible genotypes |
|---|---|
| O | OO |
•Oct 23, 1997
What phenotype is TT?
| Genotype | Definition | Example |
|---|---|---|
| Homozygous | Two of the same allele | TT or tt |
| Heterozygous | One dominant allele and one recessive allele | Tt |
| Homozygous dominant | Two dominant alleles | TT |
| Homozygous recessive | Two recessive alleles | tt |
Is there genotype AB?
Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
When a Dihybrid AABB is Selfed then the genotypes AABB AABB AABB AABB would be in a proportion of?
In a dihybrid cross the genotypic ratio can be represented as follows-assuming a cross between AABB and aabb. So, the ratio of AABB, AABb, AaBB and AaBb will be 1 : 2 : 2 : 4.
What is BB heterozygous or homozygous?
Heterozygous. An individual that contains two different alleles of a gene is heterozygous. Examples. A cow that has two alleles for a red coat is homozygous (bb). A bull with two alleles for a black coat is homozygous (BB).
What is GG genotype?
GG-genotype was associated with low levels of DHEAS in diabetic patients but not with retinopathy. We suggest a role for UCP-1 polymorphism in the pathogenesis of obesity and arteriosclerosis.
What is genotype TT?
The notation Tt means the heterozygous condition, wherein the homologous pair contains different alleles of a gene. One homologous chromosome possesses the dominant allele and the other chromosome possesses the recessive allele present for a gene.
What is FF genotype?
Your Alpha-1 genotype is FF. This means that you have two copies of the F mutation in your Alpha-1 genes. This is a rare form of alpha-1 antitrypsin deficiency. The F mutation produces a dysfunctional alpha-1 protein product.
What is genotype Oo?
There are four possible blood types and six possible genotypes. A person with blood type A could have the genotype AA or AO. A person with blood type B could have the genotype BB or BO. A person with blood type AB as the genotype AB. And a person with blood type O has the genotype OO.
What is AA in genotype?
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 genotype of AA?
If the dominant allele is labeled as “A” and the recessive allele, “a”, three different genotypes are possible: “AA”, “aa”, and “Aa”. 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.
What is the genotype of AaBb?
Predicting the genotype of offspring There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
In what proportion the genotype AaBb AaBb Aabband AaBb are produced in a typical Dihybrid f2 generation?
1:2:2:1.
What is the genotypic ratio of AABB AABB?
1 : 1 : 1 : 1 The genotypic ratio is 1 : 1 : 1 : 1.
What is the number of phenotypes possible from Aabbcc Aabbcc?
8 So, the correct option is '8'.
When AA BB and AA BB are crossed in the F2 generation the ratio of AA BB will be?
Probability of AaBb in F2 generation= 4/16. Correct answer is D.
