Mendelian inheritance

(mendē´lēn),
n.pr (Mendel's laws, mendelian laws) two basic genetic principles were established: the law of segregation and the law of independent assortment. According to the law of segregation, the genetic characteristics of a species are represented in the somatic cells by a pair of units called genes that separate during meiosis so that each gamete receives only one gene for each trait. According to the law of independent assortment, the members of a gene pair on different chromosomes segregate independently from other pairs during meiosis, so that the gametes offer all possible combinations of factors.
