In sexual reproduction, offspring are genetically different from the parents. This is because
reproduction occurs very rapidly.
only one parent is involved in reproduction.
combined genes are received from both parents.
there is less variations in daughter cells.

The sperm fertilizes the egg to produce a zygote.
Egg and sperm receive chromosomes from each parent.
In some organisms, a piece of the parent may bud off to produce offspring.

Meiosis is a process that produces gametes. Using the diagram, what do you notice about the cells produced in meiosis?
Meiosis produces 4 daughter cells each identical in number of chromosomes to the original cell.
Meiosis produces 2 daughter cells each identical in number of chromosomes to the original cell.
Meiosis produces 4 daughter cells each with half the number of chromosomes of the original cell.
Meiosis produces 7 daughter cells each with half the number of chromosomes of the original cell.
