Gene Mapping : An Overview MCQ - Practice Questions with Answers

The map distance between genes A and B is 3 units, between B and C 10 units, and between C and A 7 units. The order of the genes in a linkage map constructed on the above data would perhaps be

The frequency of recombination between gene pairs on the same chromosome as a measure of the distance between the genes was explained by:

What map unit (Centi Morgan) is adopted in the construction of genetic maps?

Find out the gene sequence on a chromosome based on the following data:

In the following questions, a statement of assertion (A) is followed by a statement of reason (R)

(1) If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark A

(2) If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark B

 (3) If Assertion is true statement but Reason is false, then mark C

(4) If both Assertion and Reason are false statements, then mark D

Assertion: Gene mapping allows for the identification of the location of genes on a chromosome.

Reason: Gene mapping involves the analysis of recombination frequencies, which are influenced by the physical distance between genes on a chromosome.

In the following questions, a statement of assertion (A) is followed by a statement of reason (R)

(1) If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark A

(2) If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark B

 (3) If Assertion is true statement but Reason is false, then mark C

(4) If both Assertion and Reason are false statements, then mark D

Assertion: Gene mapping can be used to study the evolution of species.

Reason: By comparing the location of genes between different species, researchers can gain insights into the evolutionary history of those species.

What is the significance of a recombination frequency of less than 50% between two genes?
 

How are genetic maps used in the sequencing of whole genomes?
