Diploid cells are typically produced by which process?

• A. Mitosis
• B. Meiosis
• C. Fertilization
• D. Aneuploidy

Answer: (A)

Diploid cells carry two complete sets of chromosomes, and the process that copies the genome and distributes it evenly to two daughter cells, preserving that two-set number, is mitosis. In mitosis, a diploid parent cell is divided to form two genetically identical diploid daughter cells, which is how organisms grow and replace worn-out cells. Meiosis, by contrast, halves the chromosome number to produce haploid gametes, which is essential for sexual reproduction but not for generating typical diploid cells. Fertilization combines two haploid gametes to restore diploidy in a zygote, which then can divide by mitosis to form many diploid cells. Aneuploidy involves abnormal chromosome numbers and is not a normal way to produce diploid cells.
