Genetic interaction between male mating strategy and sex ratio in a marine isopod
Article Abstract:
The genetics of the Paracerceis sculpta isopod crustacean, whereby three three different types of males, distinguishable by behavioural and morphological phentotypes, coexist, is investigated. It is suggested that the phosphoglucomutase (Pgm gene) is closely related to the single controlling genetic locus of the male phenotype. An autosomal gene and extrachromosomal factor and the primary sex determination loci interact causing a change in sex. The model suggest the control of polymorphism in male behaviour by mendelian segregation of alleles at the alternative mating strategy.

Thumbs down to the sewer rat: the diseases carred by sewer rats have accounted for more human deaths than all the wars in history combined
Article Abstract:
The common sewer or brown rat is the one seen going through garbage other human waste. They will eat anything and are frequently carriers of disease. They are more likely to attack than other species of rats, especially when cornered.
