Question 1

Answer · 2026-09-16T11:21:56.814Z

here are the answers for Question 2: 2.1.1 a) The phase represented in diagram II is Metaphase II*. b) Part A represents the spindle fibers*. 2.1.2 The type of cell that results from meiosis is a gamete (or sex cell). 2.1.3 Based on the diagrams showing 4 homologous pairs, the cell at the beginning of meiosis had 8 chromosomes. 2.1.4 a) The term for abnormal meiosis (failure of chromosomes to separate) is non-disjunction*. b) The genetic disorder that would result in humans if this abnormal meiosis occurs in chromosome pair number 21 is Down syndrome* (or Trisomy 21). 2.1.5 The cell in diagram II does not belong to a human because it contains only 4 chromosomes. A normal human cell (gamete) would contain 23 chromosomes. Drop the next question 📸
