Types of Reproduction

2. We will be focusing on genetic material and how it is passed from parent to offspring.
All living things pass on their traits to offspring but there are two different types of reproduction

3. Asexual Reproduction
Reproductive process that only requires one parent so the offspring gets 100% of its genetic material from that parent
offspring are identical to the parent (clone)
most microscopic and unicellular organisms can reproduce asexually
A few plants and animals can use this method
Also called:
Binary fission, budding, regeneration

4. Aesexual Reproduction
Only requires one parent
No sharing of genetic material
Offspring is identical to parent
No diversity

6. Asexual Reproduction Parent (tall) Tt offspring (tall) Tt

7. Examples of Asexual Reproduction
protists
fungi
hydra
ferns
starfish
bacteria

8. Sexual Reproduction
Reproductive process that requires two parents and offspring receive 50% of their genetic material from each parent
Offspring are different from either parent
Most multicellular organisms reproduce sexually

9. Sexual Reproduction Reproduction that involves two parents
Genetic material is combined
The offspring are different from either parent
Leads to more diversity

11. Fertilization (combined genetic material)
Sexual Reproduction
Parent (tall) Tt
Parent (tall) Tt
Fertilization (combined genetic material)
offspring (tall) TT
offspring (tall) Tt
offspring (tall) Tt
offspring (short) tt

12. Parthenogenesis Organisms that can reproduce asexually and sexually
The female can give birth without a male
aphids
snails
some plants
hammerheads
starfish
Kimodo dragon

13. Hermaphroditic Reproduction
Organisms that can reproduce asexually and sexually
they have male and female sex organs or they can switch sexes
snails
slugs
most plants
some fish
earthworms

Parthenogenesis
Hermaphroditic Reproduction
* more genetic diversity
* can adapt and change
* easier to evolve
* expend energy looking
for a mate
* length of gestation
* usually occurs faster
* don’t have to find a mate
* reduces genetic
mutations
* no new genetics
* no diversity
* limited evolution
* usually occurs faster
* don’t have to find a mate
* reduces genetic
