Asexual and Sexual Reproduction

Asexual reproduction: a single parent passes on all its genetic material to each of its offspring

Sexual reproduction: two parents form gametes that each contribute half the genetic material to the new offspring; sex cells have half the number of chromosomes

Both:Produce offspring and offspring have genetic material of parents

Benefits

Asexual reproduction: fast

Sexual reproduction:genetic variation

Methods of Asexual Reproduction

Binary FissionBuddingVegetativeMitosis and Cell Division

Reproduction

3

Binary Fission:Used in prokaryotesProduces identical offspringTwo steps 1.DNA is copied 2.New cell membrane divides cell

Examples:bacteria, amoeba, paramecium

Budding:New individual splits off from original parentParent remains

Examples:yeasts, sponges, hydra

Reproduction

Vegetative (propagation):plants produce new individuals from various plant parts without seeds

Examples:Seed Plants

Mitosis:a mother cell produces two daughter cells (identical)

for growth and replacement of damaged cells

Examples:all organisms
