Answer:
18
Step-by-step explanation:
By mitosis, 36 chromosome numbers are preserved in mitosis as the chromosomes duplicate prior to the division. Now In meiosis the chromosome number would be 18 as the chromosomes do not duplicate but the pairs split producing a haploid cell. This allows gametes which are haploid to fuse with another gamete and produce a new cell with the diploid number of chromosomes again but with the genetic material of two separate individuals mixed.
