The Law of Segregation states that:

A) gene pairs assort independently of each other during gamete formation.
B) differing characters in organisms result from two alleles that separate in gamete formation, such that each gamete gets only one of the two alleles.
C) differing characters are the result of either the homozygous dominant or the homozygous recessive condition.
D) phenotypes are always determined by genotypes.
E) one allele of a pair must always be dominant and the other must always be recessive.
