5.1 Mitosis

1 (a) The life expectancy of a sheep is ten to sixteen years. Dolly died at the age of six.

Why was the life span of Dolly shorter than normal? [3 marks]

(b) Explain how mitosis maintains genetic stability in an organism. [10 marks]

(c) Discuss some of the ethical issues concerning the cloning of humans. [10 marks]

Discuss the significance of mitosis in organisms. [7 marks]

5.2 Meiosis

2.(a) Explain briefly how meiosis makes genetic variation possible. [10 marks]

(b) Using a cell of 2n=4, explain how meiosis II is a type of mitosis. [10 marks]


“Dolly” the sheep was the first vertebrate cloned from the cell of an adult animal in 1996. The nucleus was taken from the mammary gland cell of a six-year-old sheep.

Meiosis is involved in the production of gametes for sexual reproduction. Offspring produced by sexual reproduction differ genetically from the parents.

Cell division through meiosis is made of meiosis I and meiosis II. Meiosis II is a type of mitosis division.
