How would genetic variation be affected if, during meiosis i, maternal chromosomes always lined up together on one side of the metaphase plate and paternal chromosomes always lined up on the other side (ignoring the effects of crossing over)? see section 13.2 ( page 281) ?

If during meiosis I, maternal chromosomes always lined up together on one side of the metaphase plate and paternal chromosomes always lined up on the other side, Gametes would contain either maternal chromosomes only or paternal chromosomes only. So different combinations would not be produced in gametes.
