Law of Segregation:
A pair of alleles for a pair of contrasting characters are brought together in a hybrid, they remain associated but not blend, and they segregate into gametes during gamete formation. This law is based on the fact that the two factors of a character present in an individual do not get mixed up (blending) and both the traits are recovered as such in the F2 generation though one of these is not seen at the F1 stage. During gametes or spore formation, factors of a pair separate or segregate from each other, so that a gamete carries only one factor of a character. This ensures the purity of gametes. Of course a homozygous parent produces all gametes that are similar while a heterozygous will produce two type gametes each having one factor with equal proportion. This law is universally applicable.
