Which statement best explains why meiosis produces haploid cells rather than diploid cells? a. Haploid cells join to form an organism that has half the number of chromosomes as the parent. b. Haploid cells join to form an organism that has a complete set of chromosomes. c. Haploid cells join to form an organism that has double the number of chromosomes as the parent. d. Haploid cells join to form an organism that is genetically identical to the parent.



Answer :

B.

A is wrong because if an organism had half the chromosomes, it'd die.
C is wrong because if it had twice the number (as with a tetraploidy), it'll also die.
D is wrong because crossing over. (Also because maternal and paternal cells form the child)

b is correct                                                                                                                         Haploid cells join to form an organism that has a complete set of chromosomes.
