A germ cell with 46 chromosomes undergoes meiosis. Which outcome regarding genetic variation arises through independent assortment during metaphase I?

A)Increased fidelity of DNA replication
B)Decreased risk of chromosomal aneuploidy
C)Novel combinations of maternal chromosomes
D)Uniform distribution of homologous alleles

💡 Explanation

Independent assortment shuffles maternal and paternal chromosomes randomly during metaphase I of meiosis, leading to novel combinations in daughter cells because each chromosome pair aligns independently; therefore, the daughter cells have varied genetic makeups, rather than simply identical copies or a uniform distribution. This differs from recombination or DNA repair.
