## How do you determine the number of different genotypes?

The number of different genotypes is 3 n where n = number of genes. For simple dominant–recessive relations, the number of different phenotypes is 2 n , where n = number of genes.

## Can there be 4 genotypes?

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 many genotypes does a gene have?

With one gene controlling a trait we have three possible genotypes, AA, Aa and aa and depending on the allelic interactions (dominance or incomplete dominance) we can have two or three phenotypes. As more and more genes control a trait, a greater number of genotypes are possible.

## What are the 3 types of genotype that can form?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous. Homozygous dominant means that a person has two…

## What is the number of phenotypes possible from AaBbCc AaBbCc?

There is a formula to know the number of possible phenotypes from two parents which is \${2^n}\$ in which n describes the number of pairs of characters. In the above cross\$AaBbCc times AaBbCc\$, there are three pairs of characters which are Aa, Bb, Cc. Therefore, the number of possible phenotypes are \${2^3} = 8\$.

## Can AA and SS marry?

AC is rare whereas AS and AC are abnormal. Compatible genotypes for marriage are: AA marries an AA. … And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.

## How many phenotypes are possible?

A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.

## How do you know your 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.
