Quick Answer: What are 3 examples of genotype?

What is an example of a genotype?

The term just means “the genes a particular organism has.” Any example of a genotype would just be a chart of a particular living thing’s chromosomes, or DNA molecules responsible for various genetic traits.

What is a genotype and give an 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 are the 3 possible genotypes for a trait?

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.

What are 5 examples of genotype?

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.

Is BB a genotype?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. … In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

Is brown hair a genotype?

Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.

Is being tall a genotype?

For most individuals, though, height is controlled largely by a combination of genetic variants that each have more modest effects on height, plus a smaller contribution from environmental factors (such as nutrition). More than 700 such gene variants have been discovered and many more are expected to be identified.

What are the 4 genotypes?

However, a fly that has a normal body color may have the homozygous genotype EE or the heterozygous genotype Ee. Things get slightly more complex when considering two genes. For instance, a wild-type fly (with red eyes and a yellow body) has one of four possible genotypes: EEBB, EEBb, EeBB, and EeBb.

How do I find out my genotype?

If you prefer finding out your genotype with the help of a blood test, you can visit the hospital nearby, and the doctor will take the blood sample from your arm. When they have enough blood, they take it for analysis to the laboratory. The laboratory test determines the level of hemoglobin in your blood.

Can As marry AA?

Compatible genotypes for marriage are:

AA marries an AS. You’ll end up with kids with AA and AS which is good. But sometimes if you’re not lucky all the kids will be AS which limits their choice of partner. AS and AS should not marry, there is every chance of having a child with SS.
