One of the most remarkable evolutionary processes, the more striking since it has occured before our eyes, has been the rise and spread of melanism and melanochroism amongst the Lepidopetera. Commencing about 1850 in the Manchester area in England wi

The inheritance of melanism in hybrids between continental Tephrosia crepuscularia and british T. Bistortata, with some remarks on the origin of parthenogenesis in interspecific crosses

Autor: J. W. Heslop Harrison

Publikováno v: Genetica. 9:467-480

1. In hybrids between BritishTephrosia bistortata and melanic ContinentalT. crepuscularia the melanism behaves in inheritance as an ordinary Mendelian dominant. 2. This is unlike the state of affairs when the melanism is introduced by BritishT. crepu

Induced changes in the pigmentation of the pupœ of the butterfly P ieris napi L., and their inheritance

Autor: J. W. Heslop Harrison

Publikováno v: Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character. 102:347-353

It has, of course, long been known that the pigmentation of the pupae of the two lepidopterous species, Pieris brassicœ L. and P. rapœ L. (Poulton, 1887), is influenced by the colour of the light to which the larvae from which they are developed ar

A further induction of melanism in the lepidopterous Insect, S elenia biiunaria esp., and its inheritance

Autor: J. W. Heslop Harrison

Publikováno v: Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character. 102:338-347

The subject of the experimental induction of melanism in the Lepidoptera, by feeding the larvæ of the species employed on food artificially charged with manganese or lead salts, has already been discussed in a former paper (Harrison and Garrett, 192

Rosa Sabini and R. Wilsoni are reciprocal crosses between R. pimpinellifolia and some Tomentosa microgene. Rosa pimpinellifolia is a balanced tetraploid, both the egg cell and the generative nucleus possessing 14 chromosomes. The Tomentosa microgenes
