Defining regions of the Y-chromosome responsible for male infertility and identification of a fourth AZF region AZFd by Y-chromosome microdeletion detection. Despite this, both in vivo and in vitro capacitation enable the spermatozoa to undergo fusion of the plasma and outer acrosomal membrane during the acrosome reaction and thus proceed to subsequent fertilization.

Drosophila are known to exhibit grooming behaviors that are executed in a predictable manner. Thus while the presence of a single Y chromosome is necessary and sufficient to generate a male gonadal phenotype, the presence of a single X chromosome, while necessary, is not sufficient to generate a full female gonadal phenotype.
