Answer the following question given this paragraph: The process that produces haploid gametes is meiosis. Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of the organisms. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair. Two cell divisions occur during meiosis, and a total of four haploid cells are produced. The two cell divisions are called meiosis I and meiosis II. The overall process of meiosis is summarized in Figure below . You can watch an animation of meiosis at this link: http://www. youtube. com/watch?v=D1_-mQS_FZ0 . Q: What is the type of cell division where the number of chromosomes is reduced in half? Choices: - cloning - mitosis - interphase - meiosis A:
meiosis
