Question

(a)What are different reproductive patterns?Describe all three with proper examples​

Answer 1

Answer:

Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis.

Answer 2

There are two types of reproduction: asexual and sexual reproduction.

Explanation:

• Only one parent is required for asexual reproduction.
• There are many types of asexual reproduction. There are four major types:
• 1) Binary Fission: Single parent cell doubles its DNA, then divides into two cells. Usually occurs in bacteria.
• 2) Budding: Small growth breaks off on the surface of the parent, resulting in the formation of two individuals. Occurs in yeast and some animals.
• 3) Fragmentation: Organisms break into two or more fragments which develop into a new individual. Occurs in many plants, as well as some animals (such as coral, sponges and starfish).
• 4) Parthenogenesis: An embryo develops from an uninfected cell. Occurs in invertebrates, as well as some fish, amphibians and reptiles.
• Sexual reproduction requires two parents. Each parent contributes a gamete – a sex cell that contains half of the normal DNA of a regular body cell. Gametes in males are sperm and in females gametes are eggs.
