A)The zygote undergoes mitosis to form a multicellular embryo, which becomes a fetus and then an infant. Meiosis, which reduces the amount of genetic material by half, occurs only in the sex cells of the testes and ovaries. When the two sex cells combine during fertilization, the total number of chromosomes present in the offspring's cells is 46, not 50.
B)The zygote undergoes mitosis to form a multicellular embryo, which becomes a fetus and then an infant. Meiosis, which reduces the amount of genetic material by half, occurs only in the sex cells of the testes and ovaries. When the two sex cells combine during fertilization, the total number of chromosomes present in the offspring's cells is 46, not 50.
