Empirical Evidence for Son-Killing X Chromosomes and the Operation of SA-Zygotic Drive

BACKGROUND Diploid organisms have two copies of all genes, but only one is carried by each haploid gamete and diploid offspring. This causes a fundamental genetic conflict over transmission rate between alternative alleles. Single genes, or gene clusters, only rarely code for the complex phenotypes needed to give them a transmission advantage (drive phenotype). However, all genes on a male's X ...

Description de Tunga bonneti n. sp. du Chili (Siphonaptera : Tungidae) et notes sur sa spécificité, sa chorologie, son dermecos et sa phénologie

Smit (1968) misreported Tunga libis from Chile. Here we describe this flea as a new species. We analyzed free life females, male and embedded females. Moreover, we include data about its natural history and biology. These data will allow a better understanding about other Tunga fleas, and particularly for collecting males, which remain unknown to date.

Le triangle hippocratique dans le monde gréco-romain: le malade, sa maladie et son médecin

connexion with the remainder of the book, and I cannot see what purpose it serves. Chapters two to five comprise the bulk of the book and are by far the best and the most rewarding of study. A good account is given of lead mining in the ancient world, of smelting and of cupellation, and there is also much information on the lead mines of antiquity and an excellent chapter on the production and ...

Le fibromatosis colli ou torticolis congénital: son diagnostic et sa prise en charge à propos de deux cas

Le fibromatosis colli (FC) est pseudotumeur rare du muscle sterno-cléido-mastoïdien (SCM), à l'origine d'un torticolis dit congénital chez le nouveau-né ou le nourrisson. Le mécanisme étio-pathogénique de sa survenue est sujet à controverse. Son diagnostic fait appel à l'échographie qui permet de mettre en évidence un épaississement caractéristique du muscle. Nous rapportons deux cas diagnostiq...
