Question

All genes located on the same chromosome ______.

विकल्प

• Form one linkage group

• Will not from any linkage groups

• Form interactive groups that affect the phenotype

• Form different groups depending upon their relative distance

Answer 1

All genes located on the same chromosome form one linkage group.

Explanation:

All genes located on the same chromosome collectively form a linkage group. This is because genes on the same chromosome tend to be inherited together during meiosis, not assorting independently as genes on different chromosomes do. The number of linkage groups in an organism equals the haploid number of chromosomes, meaning each chromosome represents one linkage group. The intensity of linkage depends on the distance between genes on that chromosome, but they still form a single linkage group overall.
