Question

If a character is controlled by $5$ alleles of a gene, calculate the possible genotypes in population

• A. $12$
• B. $17$
• C. $14$
• D. $15$

Answer 1

The correct option is D $15$

Number of genotypes for multiple alleles is $\frac{n}{2}(n+1)$. Here 'n' is number of alleles.
$\therefore$ $n=5$
$\therefore$$\frac{n}{2}(n+1)=\frac{5}{2}(5+1)=15$
$\therefore$ Number of genotypes in population is $15$.
