Answer:
Crossing over, independent assortment and random fusion of gametes
Step-by-step explanation:
Sexual reproduction creates variations by any of the three processes:
A) Exchange of genetic material between the non-sister chromatids of homologous chromosomes during prophase I of meiosis produce new gene combinations.
B) Independent assortment of homologous chromosomes towards opposite poles during anaphase I of meiosis I produce genetic variations among the daughter cells.
C) The random fusion of the gametes formed by meiosis further add genetic variations.
