Science 9 Reproduction and DNA Cheat Sheet (DRAFT) by


This is a draft cheat sheet. It is a work in progress and is not finished yet.

Asexual vs Sexual pro con

alot of offspring quickly, large colonies can form quick and compete with others, need no energy to mate
diseas­e/n­eg.m­ut­=de­aths, compete food and space, bad condit­ion­=wi­peout colony
genetic diversity, ext. little energy find mate, more offspring can exist after disaster, int. more protection and care to offspring
int. more energy­/risk to mate, fewer offspring, ext. gamate­s/e­mbr­yos­/of­fsp­rings unprot­ected

Stages of Sexual Reprod­uction

egg and sperm together; same place, same time
gametes fuse to form zygote
zygote develops into an embryo (unborn or unhatched offspring in the process of develo­pment)

Asexual reprod­uction

binary fission
