Homeostasis - Essay Example A natural process in which certain characteristics are transmitted from parents to off springs. The transmission of these characteristics from parents to off springs depends on the genetic makeup of parents (Cummings,8). Any abnormality in the genetic machinery will lead to abnormal products and thus abnormal characteristics. Regarding the mode, in case of abnormality in the genetic machinery in the parents, the transmission of defeat is subject to abnormality in parents. Autosomal includes autosomal dominant and autosomal recessive. The second is dominant and recessive. Further these patterns of inheritance depends on the defective genetic material transmission through sex chromosomes.
