Popis:	Scanning microdensitometry inAedes aegypti (L.) has revealed an extended range of DNA levels among the spermatozoa of sex-ratio distorting males compared with their normal counterparts. Fewer than 1% of spermatozoa contain less than the 1C level of DNA but more than 20% include greater quantities. Since this variation is identified with morphologically abnormal spermatozoa, it is considered to be a direct consequence of preferential X-chromosome breakage during male meiosis and hence of meiotic drive.
