BIOLOGY QUESTION BANK5-13
“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.
