A cell that contains one member of each chromosome pair | Haploid |
the statement that the members of each pair of alleles separate when gametes are formed is known as the law of? | Segregation |
The principle that states that alleles of different genes separate independently of one another during gamete formation is the law of? | independent Assortment |

Genetics | Study of heredity |
gene | located on chromosomes, segments of DNA |
