Question

A diploid organism is heterozygous for 4 loci, how many types of gametes can be produced?

Answer 1

The eight separate gametes are obtained during meiosis, if an organism is heterozygous at the four loci with example Aa, Bb, Cc, and Dd. The organism is heterozygous and gamete produced by an organism such as 2n where n= number of the loci present in it and gametes obtained from the 4 loci are $2^4 =16$.

Complete answer:
Heterozygous organisms contain different pairs of alleles and are also known by the name diploid organism. For example Aa, Bb, Cc, Dd obtained during the meiosis and segregated into the 8 different gametes and also known by the type heterozygous. But diploid organisms will produce 16 different gametes if the genes are not linked. But the gametes will reduce their number as the genes that are linked together during the meiosis in case of genes are linked.

Genes that have fixed positions in the locus and found in the chromosomes. And in the case of homozygous organisms contain the same alleles of the gene but in the case of heterozygous organisms contain different alleles of the genes. For example in case of homozygous allele AA/aa and in the heterozygous present alleles Aa/ Bb.
For example diploid organism A, B, C, D
A, b, c, d
In case of heterozygous four loci present with the four characters i.e. Aa, Bb, Cc, Dd. And in case.

Hence, the correct answer is option (B).

Note: Heterozygous organisms contain different alleles and also known by diploid organisms and four loci that are heterozygous will have different contrasting characteristics. Single or more genes that’s present on the chromosomes at a fixed position known as Loci.
