26) i) mitosis, ii) both, iii) meiosis, iv) meiosis, v) both

i) Mitosis
In mitosis, the daughter nuclei are always genetically identical to the parent cells or nucleus.

ii) Both
In order to carry out nuclear division, both processes must involve all chromosomes being replicated.

iii) Meiosis
Gametes can only be produced by meiosis. Since gametes are haploid, they must be formed by meiosis as mitosis only forms diploid cells.

iv) Meiosis
Haploid nuclei are only formed by meiosis.

v) Both
Genetic material always appears as distinct chromosomes in both processes.
