What are the four genotypes of blood?

The different possible genotypes are AA, AO, BB, BO, AB, and OO.

Can there be 4 genotypes?

If you are given a male with a yellow body and red eyes, how can you determine its genotype? In this example, there are now four possible genotypes that are associated with the dominant phenotype of yellow body/red eyes. These four genotypes can produce one, two, two, and four different gametes, respectively (Table 3).

What are the 4 blood phenotype possibilities?

The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (IAIA or IBIB, respectively), or heterozygous (IAi or IBi, respectively).

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

How many genotypes are there?

Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa. With three alleles 1, 2, 3 there are six possible genotypes: 11, 12, 13, 22, 23, 33. First we must appreciate that genes do not act in isolation.

What does AA genotype 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 are the genotypes and phenotypes of blood?

There are three alleles involved, A, B, and O, and six possible genotypes: AA, BB, OO, AB, AO, and BO. The various genotypes result in four different phenotypes or blood types: A, B, O, and AB. Individuals have blood type A if their genotypes are AA or AO.

What is blood 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 a genotype and phenotype?

The genotype refers to the genetic material passed between generations, and the phenotype is observable characteristics or traits of an organism.

What are 5 examples of genotypes?

Examples of Genotype:

  • Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
  • Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
  • Lactose intolerance.

What are the six 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.

What are the types of phenotypes?

Just a few of the countless examples of the phenotypes of living things follow.

  • Eye color.
  • Hair color.
  • Height.
  • Sound of your voice.
  • Certain types of disease.
  • Size of a bird’s beak.
  • Length of a fox’s tail.
  • Color of the stripes on a cat.

How many genotypes are there with 4 alleles?

4 alleles there are 1 + 2 + 3 + 4 = 10 genotypes.

What are genotypes examples?

Genotype examples

A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes, they must be homozygous for the blue eye allele.

What is genotype BB?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
