This principle states that alleles separate during gamete formation:

principle of segregation
principle of independent assortment
principle of multiple alleles
principle of dominance and recessiveness

2. In each case where Mendel crossed true breeding plants as parents, the offspring displayed only one of the two traits seen in the parents. This observation supports which principle of genetics?

independent assortment
segregation
allele frequency
dominance and recessiveness

3. A plant that has purple flowers is crossed with one that has white flowers. The offspring were half white and half purple. What were the genotypes of the parents?
