Azf deletions y-chromosome sex linked traits in Cessnock
One set of chromosomes comes from the mother, while the other comes from the father. This exchange occurs as a random event during the formation of sperm cells in the affected person's father. Because only males have a Y chromosome, in Y-linked inheritance, a mutation can only be passed from father to son.

Yet, confirmation of both the existence and functional properties of the RPS4Y2 protein are prerequisites for any further developments. Ferlin, A. Two long homologous retroviral sequence blocks in proximal Yq11 cause AZFa microdeletions as a result of intrachromosomal recombination events.

- In recent studies, partial deletions of the azoospermia factor c region AZFc on the Y-chromosome have been detected in males with infertility problems. However, there has been a lot of debate about their significance.
- If a gene is found only on the X chromosome and not the Y chromosome, it is said to be a sex-linked trait.
- Ricardo Jorge, Lisboa, Portugal. These are of importance for male fertility since they are home to genes required for spermatogenesis.
- Y chromosome infertility is a condition that affects the production of sperm and causes male infertility, which means it is difficult or impossible for affected men to father children. An affected man's body may produce no mature sperm cells azoospermia , fewer than the usual number of sperm cells oligospermia , or sperm cells that are abnormally shaped or that do not move properly.
