All gens located on the same chromosome

A

from different groups depending upon their relative distance

B

from one linkage group

C

will not from any linkage group

D

from interactive groups that dffect the phenotype

Text Solution

Verified by Experts

The correct Answer is:
B
All the genes, present on a particilar chormosome from al linkagr group. The number of linkage froup of a species correspond to the total number of different chromosomes of the species. It is not simply thr nomber of chromosomes in haploid set.
e.g., in human male = 22 pairs of autosomes + 1X-chrmosome + 1Y-choromosme i.e., 24 linkage groups and in femele = 22 pairs autosomes + 2X-chromosomes i.e., 23 linkage groups.
while options (a), (c ) and (d) are incorect.
