Fertilisation
 Union of an oocyte and a spermatozoon to give rise to a zygote
 Fertilization is a ‘‘choreography’ of complex and highly coordinated
processes.
 Dictates the hundreds of different cell types and the positional information for the ~1012 cells that constitute a human being
Female and male genomes
 Successful fertilisation relies on adequate maturation: absolute requirement for the production of haploid gametes with high developmental competence
