Question

Genetic map is one that

• A. Establishes sites of the genes on a chromosomes
• B. Establishes the various stages in gene evolution
• C. Shows the stages during the cell division
• D. Shows the distribution of various species in a region

Answer 1

The correct option is A

Establishes sites of the genes on a chromosomes

Tha correct option is A.

Explanation of the correct option:

1. Gene map is also known as linkage map.
2. Gene mapping shows relative location of genetic markers on a chromosome.
3. It is used to identify the locus of a gene on a chromosome.
4. It also gives information about the distance between different sites within a gene.

Explanation of the incorrect options:

Option B:

Evolutionary biology is used to study the various stages in gene evolution.

Option C:

The study of cell cycle helps in understanding the different stages of cell division.

Option D:

The branch of biology that deals with the study of distribution of various species in a region is called biogeography.

Final answer: Gene map is one that establishes sites of the genes on a chromosome.
