Answer: One of these principles, now called Mendel's Law of Segregation, states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. ... A gene can exist in more than one form or allele
Mendel's law of segregation states that genes occur in pairs and that each gamete receives only one allele of each pair (in other words, the alleles segregate). An individual who has a copy of the 1 allele and a copy of the 2 allele passes on allele 1 to 50% of the gametes and allele 2 to the other 50% of the gametes.
