Question

How many groups of linked genes are there in humans?

Answer 1

Linked genes:

1. A linkage group is a collection of genes that stay together throughout meiosis or inheritance.
2. One linkage group is represented by a chromosome. The haploid chromosomal number of an organism is roughly equivalent to the maximum number of linkage groups.
3. However, rather than a haploid or diploid number, the linkage group relates to the total number of distinct chromosomes in that species.
4. Human males contain 24 linkage groups (46, XY), which translates to 22 autosomes and a 'X' and a'Y' chromosome.
5. A human female has 23 linkage groups (22 autosomes and an X chromosome).
