The number of linkage groups in humans is?
- A
1/21
- B
23
- C
1/23
- D
1/24
Option B is correct since the number of linkage groups in humans is equal to the haploid number of chromosomes. The linkage groups refer to all the genes on a single chromosome. These groups are inherited together in an individual. The chromosomes in humans are 46 and their haploid number is 23. So linkage groups are also 23. Option A is incorrect since it states 1/21 which is wrong. Option C is incorrect since it states 1/23 which is wrong. Option D is incorrect since it states 1/24 which is wrong.
