With reference to the Sex chromosomes, consider the following statemen...
Around one in 500 men could be carrying an extra X or Y chromosome, most of them unaware, according to researchers at the universities of Cambridge and Exeter.
  • This puts them at increased risk of diseases such as type 2 diabetes, atherosclerosis and thrombosis.
  • Sex chromosomes determine our biological sex. Men typically have one X and one Y chromosome, while women have two Xs. However, some men also have XXY or XYY.
  • By linking genetic data to routine health records, the team found that men with XXY have much higher chances of reproductive problems, including a three-fold higher risk of delayed puberty and a four-fold higher risk of being childless. These men also had significantly lower blood concentrations of testosterone. Men with XYY appeared to have a normal reproductive function.
Hence both statements are correct.
