A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness

But basically it's just the number of electrons 'shared' between two atoms. A single covalent bond has one electron shared (e.g any diatomic bonding of the Group 7 elements)
Double covalent bonds have 2 electrons shared (e.g in the bonding of Carbon Dioxide)
Triple covalent bonds have 3 electrons shared (e.g in the bonding of diatomic Nitrogen)
Move covalent bonds make the molecule stronger
