Meiosis results in the formation of four genetically different haploid cells. An error occurs during the process of meiosis with the 5th chromosome to cause Cri-du-chat syndrome. Fertilization is the union of haploid gametes to produce a diploid zygote. The deletion of the 5th chromosome occurs in the production of sex cells and therefore will transfer the syndrome to the zygote it creates.
