# Your question: Are genotypes made up of 2 alleles?

## Do two alleles make a genotype?

In a diploid organism, one that has two copies of each chromosome, two alleles make up the individual’s genotype. An example is the gene for blossom color in many species of flower — a single gene controls the color of the petals, but there may be several different versions (or alleles) of the gene.

## How many genotypes does 2 alleles have?

With 2 alleles, the number of genotypes is 1 + 2 = 3.

## How many alleles are in genotypes?

Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.

## How do you count genotypes?

The frequency of genotype AA is determined by squaring the allele frequency A. The frequency of genotype Aa is determined by multiplying 2 times the frequency of A times the frequency of a. The frequency of aa is determined by squaring a. Try changing p and q to other values, ensuring only that p and q always equal 1.

## How many genotypes are possible at a locus with five alleles?

For five alleles (n = 5), we get 15 possible genotypes and five homozygotes. For eight alleles, there are 36 possible genotypes.
