2. Asexual <strong>Reproduction</strong>:<br />
Production of offspring by a single parent through:<br />
<br />
<br />
<br />
<br />
Splitting: Binary fission in bacteria.<br />
Budding: Yeasts, plants<br />
Fragmentation: Sea stars<br />
Parthenogenesis: “Virgin birth”. Several insect species.<br />
Offspring inherit DNA form one parent only.<br />
Offspring are genetically identical to parent <strong>and</strong> siblings,<br />
unless mutations occur.<br />
Advantages:<br />
Can reproduce without a partner of opposite sex.<br />
Don’t spend time, energy, <strong>and</strong> resources to find a suitable mate.<br />
Parents pass on 100% of their genetic information to each<br />
offspring.<br />
Disadvantage:<br />
No genetic diversity of offspring.<br />
• Population less likely to survive changing environment.
