Advantages and disadvantages of sexual and asexual reproduction

In this lesson we will look at the advantages and disadvantages of both types of reproduction. We will also learn about organisms who are able to reproduce both sexually and asexually, explaining why being able to do both is an advantage.

Q4.Tick all statements which apply to asexual reproduction (4 correct statements)

Select four (4) boxes

Involves gametes The offspring are genetically identical to the parent Mitosis and meiosis are involved Genetic information is mixed There is only one parent The offspring are clones There is genetic variation in the offspring Mitosis is the only cell division which takes place

4/6

Q5.Which statement about sexual reproduction is FALSE?

It involves gametes There are 2 parents involved The offspring are genetically identical to one another, but not to the parent Genetic information is mixed

5/6

Q6.Why does sexual reproduction cause variation?

Because mitosis leads to variation Because cell division is involved Because genetic information is mixed Because all offspring of sexual reproduction are clones

Q3.Tick three advantages of asexual reproduction

Select three (3) boxes

Many genetically identical offspring can be produced if conditions are favourable It is more energy efficient The species is more likely to survive if there is a change in the environment Offspring can colonise new areas It is quicker

Q4.Why is variation in offspring an advantage?

More offspring are produced It is easier to spot differences between offspring The offspring live longer The species is more likely to survive if environmental conditions change
