Two siblings from the same parents often look different from each other. Which process mainly causes this difference?
Meiosis
Meiosis produces gametes through recombination and independent assortment of chromosomes, so siblings inherit different combinations of genes from their parents and therefore look different from each other.
Hence, meiosis mainly causes this difference.
