Vern Serratos: Number 23, the sex chromosome. Traits that are on sex-linked genes (those found on the X chromosome) show up in males more frequently than in females.
Charissa Bichsel: The X chromosome.The X chromosome is larger than the Y chromosome, and thus has more possibility of containing the gene that codes for the genetic disease.
Dawn Saha: When 1 sex is more affected than another, then you would generally look first at the sex chromosomes ( pair numberv 23), and in particualar the X chromosome.Think of the X chromosome as having an extra bit that is missing in the Y. While most of the "extra" bit is inactive there are part with extra genes......for example red/green colourblindness, types of haemophilia etc and in males there is no other X and hence no way the recessive allele in these diseases are "masked" like in females, where we they can be carriers as the other X usually has the dominant allele ( it why is rarer for females to get these diseases ! as they require BOTH parents to carry the trait, while in males its only 1, the female..remember the male passes the Y onto males)...Show more
