crossing over

fertilized egg
gamete
sex cell
independent assortment
one of Mendel's principles that states that genes for different traits can segregate independently during the formation of gametes
segregation
separation of alleles during gamete formation
meiosis I
separates homologous chromosomes, makes 2 haploid cells
meiosis II
