Mendel’s Theory of Heredity

Based on his observations, Mendel developed four hypotheses. “These speculations are known as Mendel’s hypothesis of heredity. The hypotheses explain a simple form of inheritance in which two alleles of a gene are inherited to result in one of several traits in offspring. An allele in an alternative form of a gene, and a gene is a segment of DNA that has the information to encode a polypeptide or RNA molecule.

Random Segregation of Alleles
Mendel summarized his findings in two laws: the Law of Segregation and the Law of Independent Assortment. The Law of Segregation is based on his findings from his first set of experiments. Mendel stated that heritable factors are segregated during gamete formation.

Summary
Mendel developed a theory that explained simple patterns of inheritance in which two alleles are inherited to result in one of several traits in offspring.
The law of segregation states that a pair of alleles is segregated during the formation of gametes and that each gamete has an equal chance of getting either one of the allele.
