Solution

The correct option is A One
In a diploid organism, chromosomes are always present in pairs, known as the homologous pairs. Each gene will have two alternate forms, while the gametes carry a single allele of a particular gene. Thus each chromosome carries one allele of a gene in a diploid individual.
