Laws of Heredity

In the study of heredity, Mendel was one of the contributors of scientific knowledge about how a certain characteristic or trait is inherited from the parent or ancestors to the offspring through the inheritance pattern of Mendel. In Mendel’s study, he explained that the kind of trait of a certain person can be altered or determined when a single gene is mutated.

Mendel explained that if a single gene of a certain developing offspring is being mutated, then the mutation could therefore cause a certain disease that can be inherited by the offspring. Mendel’s study and constructed law focuses mainly about the genes and the possible results of cell mutation which mainly causes disorders and diseases (Simmons, 2002).

On the other hand, in the Chromosomal Basis of Heredity study, genes are said to be basically a part of the chromosomes which can be explained by the process of mitosis and meiosis or the division of cell and thus reproducing of cell into a set of another chromosomes. Both of these two studies where not fully accepted until the further studies of science by Mendel explaining the “discrete Parental factor” which imposed that the Mendelian theory of heredity is the basic of the Chromosomal Basis of Heredity (Simmons, 2002).

Science is indeed cumulative because through the further studies and experiments of both scientists, the other scientists have eventually discovered that the chromosome has its distinct character and that its specific assortment is very essential for building a certain person’s trait development which basically explains the theory of Mendel’s genetics on the process of cytology. An evidence to justify this theory is the experiment of Thomas Haunt Morgan wherein he examined the fruit flies and found out that both Mendelian law of Heredity and Chromosomal Basis of Heredity’s processes comply with a single structure of heredity process (Simmons, 2002).
