Mendel's Law of Segregation

During the formation of gametes, the two alleles for a trait segregate from one another, so that each gamete carries only one allele for each gene. The principle that alleles separate during gamete formation.

The principle that alleles separate during gamete formation is known as Mendel’s Law of Segregation. This law states that during the formation of gametes, each gene separates from the other, resulting in each gamete carrying only one allele for each gene. This random allocation of alleles is crucial for the correct formation of gametes and the subsequent development of offspring. Mendel’s experiments with pea plants demonstrated this principle, showing that the alleles for seed color separated during fertilization, leading to the expected phenotypic ratios in the offspring.
