Asexual and Sexual Reproduction

Question 1

Different types of asexual reproduction?

Answer 1

Parthenogenesis
Cloning
Binary fission
Budding
Runners
Suckers
Tubes

Question 2

What is asexual reproduction?

Answer 2

Method of reproducing offspring that does not involve the fusion of different gametes

It results in genetically identical offspring

e.g. plants, bacteria, yeast- through binary fission, fragmentation, budding

Question 3

What is sexual reproduction?

Answer 3

In sexual reproduction, there are typically two parental contributions (egg and sperm) to each offspring.

Some animals can change their sex during their lifetime. They are called hermaphrodites.

e.g. mammals, fish, reptiles- through meiosis, gametes are produced

Question 4

Advantages and disadvantages of asexual reproduction

Answer 4

Advantage: Time Efficient; no need to search for mate, requires less energy, larger number of offspring

Disadvantage: No variation - if the parent has a genetic disease, offspring does too.

Question 5

Advantages and disadvantages of sexual reproduction

Answer 5

Advantage: Variation, Unique., organism is more protected

Disadvantage: Requires two organisms, requires more energy, less offspring
