Question

In diploid population, how many genotypes are possible for a gene having three alleles? (1) 7 (2) 8 (3) 6 (4) 10

Answer 1

Answer:

Explanation:for finding genotype we use

n(n+1)%2 so put n=3 we get 6 as answer

Answer 2

Answer:

The number of genotypes possible are 6.

Explanation:

To find number of genotypes we can use formula

= n(n+1)/2

As given in question n=3

= 3(3+1)/2

=3(4)/2

=12/2

= 6

Number of genotypes is 6.

In another way, lets say alleles are A, B and C

Possible combinations are

AA AB AC

AA AB AC BB BC CC

Therefore, possible genotypes are 6.

Genotype:

• The type of variant present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolise it.
• For illustration, BB, Bb, and bb could be used to denote a certain gene variant. The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype.
• In a single experiment, the genotypes at millions of sites in a genome can be determined using DNA sequencing and other techniques. Some genetics influence an individual's phenotype, or observable traits.
