Question 16

Meiosis

Answer 16

Cell divide to form gametes

Copies of the genetic information are made
2. The cell divides twice to form four gametes, each with a single set of chromosomes
3. All gametes are genetically different from each other
Gametes join at fertilisation to restore the normal number of chromosomes. The new cell divides by mitosis. The number of cells increases. As the embryo develops, cells differentiate.

Humours response

Answer 17

production of antibodies suffer from severe and frequent infections by common pathogens and unusual pathogens
