Solution
The correct option is A Fertilization and meiosis
Meiosis includes cross over which is the process of exchange of genetic material between non sister chromatids of homologous chromosomes. This process creates new combinations of traits. Fertilization is the fusion of male and female gamete to produce diploid zygote which will inherit characters from both parents and hence the new combinations of traits are produced. Thus, both fertilization and meiosis result in genetic recombination. Mitosis is the type of cell division in which two genetically identical cells are produced by a parental cell, showing no new traits. A cell division without breakdown of nuclear envelope and formation of mitotic spindle is amitosis; it can occur through cleavage, fragmentation etc., and produce genetically identical progeny. Option A is correct answer.
