The second law of Mendel, known as the Law of Segregation, establishes that during gamete formation, alleles of a gene separate or segregate, so that each gamete carries only one allele for each hereditary characteristic.

When these gametes combine during fertilization, diploidy is restored with a unique combination of alleles. This law explains the independent distribution of hereditary traits and contributes to understanding genetic variability in offspring.
