Types of Reproduction

There are two types of reproduction:

• Sexual
• Asexual

Teach Time:

Asexual Reproduction

Asexual reproduction occurs when only one parent
organism or part of that organism produces a new
organism.
Advantages: Doesn’t require a parent organism, occurs

in a shorter amount of time, and works well in a stable
environment.

Disadvantages: No genetic variation. A major

environmental change can wipe out a species.

The new organism is genetically identical to its parent.

Two kinds of Asexual Reproduction:

1)Regeneration

The ability of an animal to regrow lost parts.

Two kinds of Asexual Reproduction:

2) Vegetative Reproduction

The ability of offspring to grow from part of the
parent plant.

These parts include stems, roots and leaves.

The hydra has a growth that appears to get larger. The growth
looks like itself in the second photo.

Advantages: No need to have two organisms, quick.

Disadvantage: Leads to too many organisms that are exactly the same.

Reproduction

Advantages

Disadvantages

Sexual

More genetic Variation

Better survival in a changing
environment

Takes a longer amount of
time

Less reliable

Requires more energy

Asexual

Takes a shorter amount of time

Requires less energy

Double the rate of population
growth (under ideal conditions)

No genetic variation

less possible survival in
changing environments
