Question

Match column I with column II and select the correct option.
$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \text{A}& \text{Dominant allele}& \text{1}& \text{It gets expressed only in homozygous condition}\\ \text{B}& \text{Recessive allele}& \text{2}& \text{Both the alleles of the gene are different}\\ \text{C}& \text{Homozygous}& \text{3}& \text{Both the alleles of the gene are same}\\ \text{D}& \text{Heterozygous}& \text{4}& \text{It gets expressed in both homozygous and heterozygous conditions}\end{array}$

• A. A-1, B-2, C-3, D-4
• B. A-2, B-3, C-4, D-1
• C. A-4, B-1, C-3, D-2
• D. A-3, B-4, C-2, D-1

Answer 1

The correct option is C A-4, B-1, C-3, D-2

A diploid organism with two identical alleles for a particular gene is said to be in homozygous condition for that gene.

The one that has two dissimilar alleles for a particular gene is said to be in heterozygous condition for that gene.

The allele that gets expressed in both homozygous and heterozygous condition is known as dominant allele.

The allele that gets expressed in homozygous condition only is known as recessive allele.
