โœฆ Synopsis

The difference in percentage hatch from the two matings was small, indicating that spermatozoa were produced in superabundance so that the overall fertility of Distorter males was not greatly reduced.

The reduction in the number of spermatozoa is, however, less than expected from the number of X chromosome breaks observed, suggesting that some non-functional X bearing spermatozoa are produced (Newton, Wood & Southern, 1976).

The Distorter gene D in Aedes aegypti shows meiotic drive when associated with the male-determining M gcne, causing sex ratio distortion in favour of males. The fertility of Distorter (MD/m s) and normal (M/m-) males has been compared by mating them to a series of females at daily intervals and asse

Sex-ratio distortion has been investigated in males carrying the Y(M)-linked meiotic-drive gene D, from three different strains (Bozo, Caracas and Trinidad), paired with Chipei X-chromosomes highly sensitive to D. The effect of D was tested on its own and also associated with a 1-3 translocation (de

Recombination on the sex-chromosome of Aedes aegypti has been studied in male genotypes incorporating the sex-linked translocation T1 and the meiotic drive gene D from three different strains (Trinidad, Bozo and Caracas). The introduction of the D gene was associated with an increase in recombinati
