About Mendelian Genetics

Mendelian genetics describes inheritance patterns discovered by Gregor Mendel. Key principles include: the Law of Segregation (alleles separate during gamete formation) and the Law of Independent Assortment (genes for different traits assort independently). Dominant alleles (uppercase) mask recessive alleles (lowercase) in heterozygotes.
