Multiple Choice
What is crossing over and during which phase of meiosis does it occur?
A
Crossing over is the replication of DNA, and it occurs during interphase.
B
Crossing over is the exchange of genetic material between homologous chromosomes, and it occurs during prophase I.
C
Crossing over is the separation of sister chromatids, and it occurs during anaphase II.
D
Crossing over is the alignment of chromosomes at the equatorial plate, and it occurs during metaphase I.
Verified step by step guidance1
Understand the concept of crossing over: Crossing over is a process where homologous chromosomes exchange genetic material. This increases genetic diversity in gametes.
Identify the correct phase of meiosis: Crossing over occurs during prophase I of meiosis. This is when homologous chromosomes pair up and exchange segments.
Differentiate crossing over from other processes: Crossing over is not the replication of DNA, separation of sister chromatids, or alignment of chromosomes at the equatorial plate.
Recognize the significance of crossing over: It contributes to genetic variation by recombining alleles between homologous chromosomes.
Review the stages of meiosis: Prophase I is the first stage of meiosis I, where crossing over occurs, followed by metaphase I, anaphase I, and telophase I.
