When do homologous chromosomes pair?
Understand the Problem
The question is asking about the specific stage in meiosis when homologous chromosomes come together to form pairs. This typically occurs during prophase I of meiosis, where they align along the metaphase plate for genetic recombination.
Answer
prophase I of meiosis
Homologous chromosomes pair during prophase I of meiosis.
Answer for screen readers
Homologous chromosomes pair during prophase I of meiosis.
More Information
During prophase I of meiosis, homologous chromosomes pair up to form tetrads in a process facilitated by synapsis and genetic material is exchanged through crossing over.
Tips
A common mistake is confusing homologous chromosome pairing with sister chromatid alignment or the behavior of chromosomes in other stages of meiosis.
