1 10.6 Meiosis I in an animal cell Slide number: 1 Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Homologous pairs align at the metaphase plate. Metaphase I DNA Replication Homologous chromosomes separate, pulled to opposite poles by centromeric spindle fibers. Anaphase I Daughter cells have one chromosome from each homologous pair. Telophase I Homologous chromosomes pair during synapsis. Prophase I Meiosis I 2n = 4 Chromosomes still consist of two chromatids. Interkinesis n = 2
