Question

How many linkage groups would be revealed by careful analysis of human genetics? 

Options

• 23

• 4

• 3

• 1

Answer 1

23

Explanation:

In human genetics, the number of linkage groups corresponds to the number of chromosomes, as each chromosome represents a linkage group. Humans have 23 pairs of chromosomes, so careful genetic analysis reveals 23 linkage groups. This means that genes located on each of these 23 chromosomes tend to be inherited together due to their physical proximity on the same chromosome, forming distinct linkage groups.
