Studies on the Spermatogenesis of Some Indian Homoptera

Part IV. The heterochromosome of a Cercopid-Poophilus sp

Abstract

1. The diploid number in Poophilus is 25, and the haploid number is 12AA and X.
2. The sex chromosome segregates in the first division typical of Homoptera Auchenorrhyncha.
3. The sex chromosome lags (succession) in the first division and not n the second meiotic division. A detailed behaviour of the same is discussed.
