Animal Reproduction

Question 1

Budding

Answer 1

Process by which new organisms split off from pre-existing organisms. Form of asexual reproduction.

Example: Hydra

Question 2

Fragmentation and Regeneration

Answer 2

The process by which a pre-existing organism breaks into parts that regenerate into new organism. Form of asexual reproduction.

Examples: sponges, planaria, starfish

Question 3

Parthenogenesis

Answer 3

The process by which an egg develops without being fertilized. The resulting adult is haploid. Form of asexual reproduction.

Examples: Honeybees and whiptail lizards

Question 4

Advantages of Asexual Reproduction

Answer 4

• enables animals living in isolation to reproduce without a mate
• generation of offspring is quick
• no expenditure of energy-maintaining reproductive systems or hormonal cycles
• offsprings are identical clones of the parent, this is advantageous when the environment is stable

Question 5

Asexual Reproduction

Answer 5

Produces offspring genetically identical to the parent. Three types of asexual reproduction are:

• Budding
• Fragmentation and Regeneration
• Parthenogenesis
