Teaching Sex-linked inheritance

Sex-linked inheritance

One special pattern of inheritance that doesn’t fit Mendel’s rules is sex-linked inheritance, referring to the inheritance of traits that are located on genes on the sex chromosomes. Since males and females do not have the same sex chromosomes, there will be differences between the sexes in how these sex-linked traits —traits linked to genes located on the sex chromosomes—are expressed.
