Types of reproduction:<br />
1. Sexual <strong>Reproduction</strong>:<br />
Most common type of animal reproduction.<br />

cell) join together to create a fertilized egg or zygote.<br />
The offspring has genetic information from both parents.<br />
Offspring are genetically different from each parents<br />
<strong>and</strong> their siblings.<br />
Advantages:<br />
Ensures genetic diversity of offspring.<br />
• Population more likely to survive changing environment.<br />
Disadvantages:<br />
Cannot reproduce without a partner of opposite sex.<br />
Considerable time, energy, <strong>and</strong> resources spent to find a suitable<br />
mate.<br />
Parents only pass on 1/2 (50%) of their genetic information to<br />
each offspring.
