Genetic disease is passes through the several generations because the parents of a child may have an X or Y chromosome in their genes. Y chromosome would be more dominant trait so this would make the child have such disease. Sometimes the parent does not have the disease they still can pass it to their children if they have the gene for it. In this paper, I will analyze the transmission of genetic disease that go through several general in family. Males are indicated by square, females by circles. Individuals with the disease are colored solid black. Speculate on the genetic basis by which this disease is inherited.


Genetic is the passing on with having characteristics to move from one generation to another. The genetic proves is occurs among all the living things that include human, animal, bacteria and fungi. The molecules of genetic are also called as Deoxyribonucleic Acid (DNA), and this is not necessary that molecule is apparent just in the living things. The German botanist, Oscar Hertwig in 1876, and the Belgian zoologist, In meiosis the fatherly and maternal chromosomes get disconnected and the alleles with the qualities of a character are isolated into two diverse gametes. There are the following principles of heredity that suggested by Gregor mendel Codominance

Incomplete dominance

Multiple alleles


Polygenic inheritance

Linkage of genes

The above diagram shows that (Steven, Harry, Ben, Mike are male and suffered with genetic disease while Rose are only female with genetic disease). Genetic diseases are also associates with chromosome X that is more likely inherited with the male than female (Farabee, 2001). Basically, women's are inherent with two X chromosome (one from each parents) while male are inherent with one X chromosome (from the mother) and one Y chromosome (from the father) (Farabee, ...
