Which is required for sexual reproduction? mitosis binary fission diploid cell production meiosis mitosis binary fission diploid
dsp73
Meiosis (SEXUAL cell division) is a type of Mitosis (cell division). 
Diploid cell production happens during meiosis when the haploid (n) cells from the parents divide into TWO diploid (2n) cells (which have the complete set of chromosomes from the parents). 

Basically, meiosis is required for sexual reproduction (unless in your question you can choose more than one answer...so it'll be meiosis, diploid cell production, mitosis)
