Question

which of the two meiotic divisions halves the chromosome number? a meiosis i b meiosis ii question 36 most of the genetic variations produced by meiosis are due to the process of a crossing over. b asexual reproduction. c mutation. d karyokinesis. e gametogenesis. question 37 sexual reproductive cells are called_. a sporozoites. b lymphocytes. c zygotes. d gametes.

Explanation:

• In meiosis, meiosis I is the reduction - division where the chromosome number is halved as homologous chromosomes separate.
• Crossing - over during meiosis I exchanges genetic material between homologous chromosomes, generating most genetic variations.
• Sexual reproductive cells are called gametes. Sperm and egg are examples of gametes.

Answer:

• Question 1: A. meiosis I
• Question 36: A. crossing over.
• Question 37: D. gametes.
