Types of Reproduction Asexual Sexual
Purpose of Reproduction • To make sure a species can continue. • Definition: Reproduction is the process by which an organism produces others of its same kind.
Asexual Reproduction • A new organism is produced from one organism. • The offspring will have hereditary material uniform with the hereditary material of the parent organism. This means they will be genetically alike. • There will be very little genetic diversity.
Types of Asexual Reproduction • Budding-Offspring begins as a small growth on the parent. • Binary fission - The parent makes a copy of its DNA and divides into two organisms. • Regeneration - The ability to re-grow lost body parts.

Sexual Reproduction • A new organism is produced from two similar organisms • Requires two sex cells – egg, carrying ½ of the female chromosomes, and sperm, carrying ½ of the male chromosomes, join to form an entirely new organism. • The new organism is genetically different from the parent organisms. • There will be a lot of genetic diversity.
Organisms with Sexual Reproduction Apple Tree Hercules Beetle Multicellular organisms
Organisms with Sexual Reproduction Homo sapiens (people)
IMPORTANT! • Asexual reproduction results in offspring that are genetically identical to the parent organism and creates very few changes (diversification) of the species. • Sexual reproduction results in offspring that are genetically different from the parent organisms and can create many changes (diversification) of the species
