Multiple Choice
Crossing over is possible due to what event that occurs in Meiosis I but not in Mitosis?
A
Separation of sister chromatids
B
Formation of the mitotic spindle
C
Cytokinesis
D
Synapsis of homologous chromosomes
Verified step by step guidance1
Understand that crossing over is a process where homologous chromosomes exchange genetic material during meiosis, leading to genetic diversity.
Recognize that meiosis consists of two stages: Meiosis I and Meiosis II. Crossing over occurs during Prophase I of Meiosis I.
Identify that synapsis is the pairing of homologous chromosomes during Prophase I of Meiosis I, which allows crossing over to occur.
Differentiate between meiosis and mitosis: In mitosis, homologous chromosomes do not pair up, and thus, crossing over does not occur.
Conclude that the event unique to Meiosis I that facilitates crossing over is the synapsis of homologous chromosomes, which does not occur in mitosis.
