Multiple Choice
In which type of cell division do homologous chromosomes pair (synapsis) and form tetrads as part of the normal process?
A
Meiosis II (prophase II)
B
Both mitosis and meiosis equally, as a required step
C
Mitosis (prophase)
D
Meiosis I (prophase I)
Verified step by step guidance1
Understand that homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.
Recall that synapsis is the process where homologous chromosomes pair up closely along their lengths, which is a key event in cell division.
Identify that synapsis and the formation of tetrads (groups of four chromatids) occur specifically during meiosis, not mitosis.
Recognize that meiosis consists of two divisions: Meiosis I and Meiosis II, and that synapsis happens during Prophase I of Meiosis I.
Conclude that the correct stage where homologous chromosomes pair and form tetrads is Meiosis I (Prophase I), distinguishing it from mitosis and Meiosis II.
