How many cells does meiosis produce?
4 different cells
What does heredity mean?
What happens in interphase?
The cell prepares for cell division by growing, replicating its DNA and completing general cell processes.
Name the stages of meiosis
Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, Prophase 2, Metaphase 2, Anaphase 2 and Telophase 2
Inherited trait: eye colour/hair type/height etc.
Acquired trait: speaking another language/ riding a bicycle etc.
What is the name of the thin like structures that pull the chromosomes to opposite sides of the cell.

Genes are stored on chromosomes which are located in the nucleus of the cell
In what stage of mitosis are the chromosomes lined up in the middle.
Metaphase
True or false:
During metaphase 1 the chromosomes are lined up in pairs
