Question

A plant heterozygous for three allelic pairs, undergoes selfing, then how many genotypes regarding these alleles will be produced in F1 generation?​

Answer 1

Answer: 3^3= 27

Explanation: There is a formula for finding out the number of genotypes. 3^ n, where n is the number of heterozygous allelic pairs.

Answer 2

Answer:

The correct answer is 27.

Explanation:

Allelic interactions are known to predict phenotype from genotype through dominance. When we have one controlling gene, it produces one phenotype but three genotypes.

There is a simple formula instituted to let us know the number of genotypes in the F₁ generation. The formula is:

$Number of genotypes = 3^n$; where n is the heterozygous pairs of alleles present.

Here, the given plant is heterozygous for 3 pair of alleles, therefore,

$n = 3$

∴ $Number of genotypes = 3^n = 3^3 = 27.$
