Question

In haploids, both recessive and dominant alleles are expressed because

• A. two alleles are present for each gene
• B. more than two alleles are present for each gene
• C. only one allele for each gene is present in the individual organism
• D. alleles do not have dominant recessive relationship

Answer 1

The correct option is C only one allele for each gene is present in the individual organism

The haploid organisms contain only one set of the alleles in genome, i.e. only one allele of each gene is present. As no alternate allele is present every gene, irrespective of dominant or recessive nature, expresses itself.
In diploid organisms every individual contains two sets of the genome, which means every gene has two alleles.
