sexual reproduction | creating unique offspring from two parents through meiosis and fertilization |
Zygote | product of fertilization; first cell of new offspring |
homologous chromosomes | pairs of chromosomes with same genes; one copy inherited from each parent |
haploid | n; cell with only one copy of each chromosome |
diploid | 2n; cell with full set of chromosomes; homologous pairs |
crossing over | homologous pairs exchange DNA during prophase I of meiosis |
independent assortment | random alignment of homologous pairs during metaphase I can generate different gene combinations |
genetic diversity | different gene combinations |
