Mendel was an Austrian monk and biologist who loved to experiment with plants. Upon performing one such experiment with pea plants, he was able to discover the rules that govern heredity (i.e., the transmission of characters from parents to offspring).

WebApr 9, 2024 · This is the basis of Mendel’s First Law, also called The Law of Equal Segregation, which states: during gamete formation, the two alleles at a gene locus segregate from each other; each gamete has an equal probability of containing either allele.
