The law of dominance and the law of segregation is part of the laws of inheritance proposed by Gregor Johann Mendel. The laws were introduced after Mendel conducted a series of experiments with pea plants (Pisum sativum). His learning from the experiments was deduced in the form of two laws.

Law of Dominance and Law of Segregation Examples

Gregor Johann Mendel was a 19th-century biologist, mathematician, and meteorologist who proposed laws of inheritance, including the law of dominance and the law of alienation. He came up with these rules after his series of experiments with the pea plant. The law of dominance and the law of segregation are explained below with examples:

Law of Dominance Law of Segregation
According to this law, in the heterozygous stage, the dominant allele is the one whose traits are expressed on the other allele. In a hybrid pair, when two traits come together, the two characters do not mix with each other and are independent of each other.
The characters of this dominant allele are called dominant characters. Every gamete receives one of the two alleles during meiosis of the chromosome.
Example – Inheritance of seed shape in peas. Example – The color of the flower depends on the type of allele inherited by the offspring.
