Question

Match the following
$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \text{I. Gene}& \text{A. Homozygous}\\ \text{II. TT}& \text{B. DNA}\\ \text{III. Alternate form of gene}& \text{C. Heterozygous}\\ \text{IV. Tt}& \text{D. Allele}\end{array}$
The correct match is

• A. l-B, II- A, III-D, IV-C
• B. l-D, II-A, III-B, IV-C
• C. l-D, il-B, III-A, IV-C
• D. l-B, II-C, III-D, IV-A

Answer 1

The correct option is A l-B, II- A, III-D, IV-C

The correct match is
$\begin{array}{cc}\text{I. Gene}& \text{B. DNA}\\ \text{II. TT}& \text{A. Homozygous}\\ \text{III. Alternate form of gene}& \text{D. Allele}\\ \text{IV. Tt}& \text{C. Heterozygous}\end{array}$
Gene is the segment of DNA which has some information stored in it.
Alleles are alternate forms of genes. For example, T and t are alleles of the gene responsible for tallness.
If both the alleles of a particular gene are identical (eg: TT) in a diploid organism, then it is known as homozygous condition.
If both the alleles of a particular gene are not identical (eg: Tt) in a diploid organism, then it is called heterozygous condition.
