Develops from a zygote
Fertilization
Process in which gametes from two parents combine
Gametes
Sperm from males and eggs from females
Genetic diversity
Variety in species

Homologous chromosomes
Matching chromosomes
Sexual reproduction
Produces offspring that are genetically different from each other
