Which gender has more chromosomes?

Published in Human Genetics 2 mins read

Neither gender inherently has more chromosomes in terms of the total number. Both males and females typically have 46 chromosomes. The difference lies in the type of sex chromosomes they possess.

Human Chromosomes: A Closer Look

Humans have 23 pairs of chromosomes for a total of 46. 22 of these pairs are called autosomes and are numbered based on size. The 23rd pair determines sex. The reference stated, "The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes."

Sex Chromosome Differences

The key difference between males and females is in their sex chromosomes:

  • Females: Possess two X chromosomes (XX).
  • Males: Possess one X chromosome and one Y chromosome (XY).

Therefore, both genders still have the same number of chromosomes (46), the sex chromosomes (X and Y) are different.

Gender Sex Chromosomes Total Chromosomes
Female XX 46
Male XY 46

Summary

In summary, both males and females have the same total number of chromosomes (46). The difference is that females have two X chromosomes, while males have one X and one Y chromosome.
