In the context of meiosis, what does the principle of independent assortment state?
A
Crossing over between homologous chromosomes occurs during metaphase I, producing identical gametes by exchanging equal DNA segments.
B
Homologous chromosomes remain paired through meiosis II so that linked genes are always inherited together.
C
Alleles of different genes segregate into gametes independently of one another due to the random orientation of homologous chromosome pairs at metaphase I.
D
Sister chromatids separate during anaphase I, ensuring that each gamete receives one chromatid from each chromosome.
