Question

Quizplus · Accepted Answer

In meiosis I, duplicated chromosomes line up pair to pair in a process called synapsis, where homologous chromosomes align and form a tetrad. This allows for crossing over to occur before the separation of homologous chromosomes in meiosis I. In meiosis II and mitosis, duplicated chromosomes align along the cell equator without the pairing of homologous chromosomes. Fertilization is the fusion of two gametes, not a phase of gamete production.
