Meiosis & Genetic Variation
Meiosis is a special type of cell division that occurs in reproductive organs to form gametes (sex cells).
How many times does a cell divide during meiosis?
What is Meiosis & Genetic Variation?
"Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell."
How many times does the cell divide during meiosis?
Why is understanding the human genome important for modern medicine?
Which group belongs to the domain Archaea rather than true bacteria?
If both parents are heterozygous (Bb) for a recessive trait (b), what is the probability their child will express the trait?
Gamete Formation
Cells in reproductive organs divide to form gametes with half the number of chromosomes.
A cell copies its genetic information, then divides twice to form four gametes.
All four gametes are genetically different from each other and the parent.
Meiosis HALVES the number of chromosomes; fertilisation RESTORES the full number.
