How many phenotypes are possible with 3 genes?
three phenotypes However, three alleles can produce exactly three phenotypes when those alleles are in a dominance series.
What are the types of phenotype?
Phenotype Examples
- Eye color.
- Hair color.
- Height.
- Sound of your voice.
- Certain types of disease.

How many phenotypes and genotypes are there?
4 Phenotypes and 9 Genotypes.
What are 3 examples of phenotypes?
In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color. And phenotypes aren't just physical traits. Behavior is also considered a phenotype.
What are the 3 types of genotypes?
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp).
How many phenotypes does each trait have?
Figure 13: The possible genotypes for each of the four phenotypes. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.
What are the 3 phenotypes?
Polygenic inheritance can be explained by additive effects of many loci: if each "capital" allele contributes one increment to the phenotype. With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
How many genotypes are there?
six different genotypes A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus.
What are the 4 possible phenotypes for blood?
The four basic ABO phenotypes are O, A, B, and AB.
How many different types of phenotypes are possible in human population?
4 types The three alleles are IA, IB, and i. These three alleles combine to form 6 types of genotypes. Since IA and IB are codominant over i, there are 4 types of phenotypes possible, i.e. A, B, AB and O.
What phenotype means?
an observable trait "Phenotype" simply refers to an observable trait. "Pheno" simply means "observe" and comes from the same root as the word "phenomenon". And so it's an observable type of an organism, and it can refer to anything from a common trait, such as height or hair color, to presence or absence of a disease.
What are the 4 types of genotypes?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon)….There are four blood GROUPS:
- Type A (marker A)
- Type B (marker B)
- Type AB (blood cells have both A and B markers)
- Type O (blood cells have neither A or B markers)

What are 3 possible phenotypes?
Polygenic inheritance can be explained by additive effects of many loci: if each "capital" allele contributes one increment to the phenotype. With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
How many possible phenotypes are there among the offspring?
Figure 13: The possible genotypes for each of the four phenotypes. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.
What are the 6 blood type genotypes?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
How many genotypes are possible with 4 alleles?
10 genotypes 4 alleles there are 1 + 2 + 3 + 4 = 10 genotypes.
How do you find the phenotype?

What are the 4 phenotypes of blood?
The four basic ABO phenotypes are O, A, B, and AB. After it was found that blood group A RBCs reacted differently to a particular antibody (later called anti-A1), the blood group was divided into two phenotypes, A1 and A2.
What is blood phenotype?
The “phenotype” of any blood group refers to which antigens are detectable on the RBC, and it usually (though not always) corresponds to the genes that the patient carries. Phenotyping is used in blood banking in four main settings: For blood donors, to determine compatibility for a patient with an alloantibody.
How many genotypes has 5 alleles?
The calculator does not go beyond 5 alleles and 15 possible genotypes.
How many phenotypes are possible in a Dihybrid cross?
four possible phenotypes Thus, according to Mendel's principles, a dihybrid cross between two heterozygous fruit flies with brown bodies and red eyes (BbEe X BbEe) should yield offspring with nine possible genotypes (BBEE, BBEe, BBee, BbEE, BbEe, Bbee, bbEE, bbEe, and bbee) and four possible phenotypes (brown body with red eyes, brown body …
What are the 6 genotypes of blood?
In 1924, this blood group was classified into four antigens (A, B, O and AB) and six genotypes (AA, AO, BB, BO, OO and AB). It is one of the conventional blood group polymorphisms, which are important for genetic markers in linkage analysis, blood transfusion, personal identification and disease detection (4,5).
How many phenotypes and genotypes are possible in F2 generation?
The number of genotypes is 9. So the correct option is (D) Phenotypes-4 Genotypes-9.
What are the 8 different blood types?
In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-). Click on a blood type below to learn more. Click on a blood type below to learn more.
How many genotypes are possible with 8 alleles?
36 possible genotypes Therefore, 8 alleles of a gene can have 36 possible genotypes in the population.
How many phenotypes and genotypes are possible if a character is controlled by 5 pairs of Polygenes?
So, the correct option is '16'.
What are the 3 rarest blood types?
