During which phase of meiosis can homologous chromosomes exchange some genetic information?
A
Anaphase I
B
Metaphase I
C
Telophase I
D
Prophase I
Verified step by step guidance1
Understand the process of meiosis, which is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two consecutive divisions: meiosis I and meiosis II.
Recognize that homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.
Learn about the phases of meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I. Each phase has distinct events that contribute to genetic diversity.
Focus on Prophase I, where homologous chromosomes pair up in a process called synapsis. This is the stage where crossing over occurs, allowing homologous chromosomes to exchange genetic material.
Understand that crossing over during Prophase I leads to genetic recombination, which increases genetic variation in the resulting gametes.
