Reproduction

Sexual:

• Each gamete contains 23 cromosomes half the number of a normal body cell (23 pairs which is 46 individual)
• Involves the fusion of male and female gametes. Because  there are two parents, the offspring contains a mixture of the parents DNA.
• Flowering plants use this, they have eggs but the sperm is called pollen.

Asexual:

• Happens by mitosis.
• Only one parent, no fusion of gametes, no genetic variation (no mixing of chromosomes), the offspring are genetically identical.
• Bacteria and some plants use this.

Meiosis:

• To make gemetes with half the number of chromosomes so that when they fuse (during sexual reproduction) they produce a cell with the same number of chromosomes as a body cell.
• Involves two cell divisions.

Process:

1) Duplicates its genetic information and each chromome lines up with a pair.

2)In the FIRST division the chromosomes line up in the…
