Oog! enesis= process which gametes are produced in female animals Ovum=egg, which comes from the uneven cell split in meiosis II A Sexual Reproduction= single arouse passes copies of all of its genes to each of its offspring, some plants, hammerhead shark and the shadowy tip shark are examples Sexual Reproduction= primaeval parents each form reproductive cells that have one half the number of chromosomes.
