In human males, what is the total number of linkage groups?

In humans, there are a total of 23 linkage groups which correspond to the 23 pairs of chromosomes found in diploid cells. A linkage group is essentially a set of genes that are linked together on the same chromosome and tend to be inherited together due to their proximity. In males, as well as in females, these linkage groups reflect the autosomal chromosomes and the sex chromosomes.

Humans possess 22 pairs of autosomes and one pair of sex chromosomes (XX in females and XY in males). Although males have one X and one Y chromosome, these are counted as part of the overall 23 linkage groups rather than constituting additional groups. Therefore, the total number of linkage groups in human males is 23, representing all unique chromosomes involved in genetic inheritance.
