BIOLOGY 287 Study Guide - Quiz Guide: Chromosome, Gamete, Meiosis
Document Summary
Meiosis quiz study guide refers to chromosomes that each have a. Homologous chromosomes: corresponding chromosome from the opposite-sex parent. Diploid: a cell that contains both sets of homologous chromosomes- two sets . Haploid: a cell that contains only a single set of chromosomes- one set . Meiosis: the process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Crossing over: process in which homologous chromosomes exchange portions of their chromatids during meiosis (occurs during prophase 1) Questions: the purpose of meiosis is to create gametes (sex cells) with half the number of chromosomes as body cells; 4 cells are made that are all haploid (n-half); n=number of chromosomes: Interphase: cells undergo a round of dna replication, forming duplicate chromosomes. Prophase i: each chromosomes pairs with its corresponding homologous chromosomes to form a tetrad (+ crossing over occurs)
