Question

How many genotypes are possible in F₂ generation, if a character is controlled by 3 pairs of polygenes?

Answer 1

Polygene:

1. When a set of genes is expressed collectively, they form a specific phenotype or trait, but their separate effects are too small to notice.
2. A genotype is a set of heritable genes that can be passed down from parents to offspring in an organism. A person's genotype is the combination of alleles they have for a particular gene.
3. 3ⁿ is a general formula for the number of genotypes.
4. In the case of three pairs of polygenes, 3ⁿ=3³ =3*3*3=27
