Question

how many homozygous
genotype of human blood​

Answer 1

Answer:

As you can count, there are 6 different genotypes & 4 different phenotypes for blood type. Note that there are two genotypes for both "A" & "B" blood --- either homozygous (IAIA or IBIB) or heterozygous with one recessive allele for "O" (IAi or IBi).

Answer 2

Answer:

6 different genotypes in human gene pool

Explanation:

We can easily calculate the number of possible genotypes if we know the total number of alleles present in a gene pool.Calculation:

Formula - n(n-1) n= Total number of known alleles

For human blood group , there are 3 alleles.ie. ABO. So, n=3

By the formula ,

Possible Genotypes = n(n-1)

= 3 (3-1) = 3×2 = 6 genotypes
