-
Name one advantage of sexual reproduction.
It produces variation in the offspring.
-
Why is variation an advantage?
If the environment changes, some offspring may survive, by natural selection.
-
How can humans speed up natural selection?
By selective breeding.
-
Name one advantage of asexual reproduction.
Only one parent is needed.
-
Why is asexual reproduction more efficient?
There is no need to find a mate.
-
Is asexual reproduction faster or slower?
Faster.
-
What can asexual reproduction produce in favourable conditions?
Many identical offspring.
-
What is a disadvantage of asexual reproduction?
There is no variation.
-
Where do malarial parasites reproduce asexually?
In the human host.
-
Where do malarial parasites reproduce sexually?
In the mosquito.
-
How do fungi reproduce asexually?
By spores.
-
Why do fungi also reproduce sexually?
To give variation.
-
How do strawberry plants reproduce asexually?
By runners.
-
How do daffodils reproduce asexually?
By bulb division.
-
How do plants such as strawberries reproduce sexually?
By producing seeds.
-
Common mistake about the advantages?
