How would genetic variation be affected if during meiosis I maternal chromosomes

Question

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)?

a. Gametes would contain either maternal chromosomes only or paternal chromosomes only.
b. Gametes would contain maternal chromosomes only.
c. Gametes would contain different combinations of maternal and paternal chromosomes.
d. Gametes would contain paternal chromosomes only.

Explanation / Answer

Answer: [A] The chromosomes are pulled away from each other from the metaphase plate. Hence, all the chromosomes to 1 side are pulled one way, and all the chromosomes on the other side are pulled the other way. Eventually, each haploid cell would only contain either only maternal or paternal chromosomes if crossing over didn't occur.
