Meiosis

Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes

• the equational division of a cell into two identical copies
