Question

In a diploid individual the number of allele will be? One Two Multiple None

Answer 1

There are two alleles for each gene in a diploid individual.

Explanation:

Haploid number indicates the types of chromosomes present in an individual. In diploid individual, each chromosome is in duplicate. Two chromosomes of the same type are termed homologous chromosomes.

Two chromosomes in a homologous pair are similar as far as the length, position of centromere and the type of genes present on it are concerned.

However, a particular gene represents similar allele ( homozygous ) or different allele ( heterozygous ) on two chromosomes of homologous pair.

Thus each gene has two alleles in diploid individual, one each present on two chromosomes of homologous pair at identcal site.
