Meiosis

Question 2

The cell duplicates the genetic information and arranges itself into pairs
The pairs are pulled apart (cell divides) and some of the fathers and mothers chromosomes go into each cell
In the second division the chromosomes line up before being pulled apart which creates 4 genetically different cells

Question 4

Advantages of sexual reproduction

Answer 4

Variation in species
Can become more adapted to the environment
More disease resistant
Allows natural selection

Question 5

Advantages of asexual reproduction

Only needs one parent
Faster and takes less energy

Answer 6

Malaria -sexual in mosquito and asexually in human host
Species of fungus through spores
Plants such as strawberries

Question 7

What do different genes cause?

Answer 7
