Serenity is from Latin serenus calm, peaceful plus the suffix -itas. The first part of the word is the English adjective serene, which means calm and peaceful. The Latin suffix corresponds to our English suffix -ity and has the meaning quality or state..
Sex-linked recessive traits, or X linked recessive traits are more likely to affect males because they have one X chromosome, so if the X they received was affected, there would be nothing to dominate over the recessive allele. This leads to expression of the affected gene, resulting in a genetic disorder.
A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked. Men normally have an X and a Y combination of sex chromosomes, while women have two X's. Since only men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. Men and women can get the X-linked ones since both inherit X chromosomes.
