Genetic polymorphism for alternative mating behaviour in lekking male ruff Philomachus pugnax
Article Abstract:
Some lekking male ruff Philomachus pugnax exhibit an alternative mating behavior linked to male breeding plumage pholymorphism. These differential morph developments most likely involve a two-allele, single locus autosomal genetic polymorphism that is controlled genetically. The families are classified by paternal phenotype because females do not exhibit the behavioral phenotype for alternative mating. The influence of environmental factors is unknown because the research was conducted in captivity. Some body size was also linked to the morphism, possibly because large size was unnecessary for the alternative behavior.

Role of a p53 polymorphism in the development of human papillomavirus-associated cancer
Article Abstract:
New research on the role of the cellular tumour-suppressor protein p53 in the development of papillomavirus-associated cancer shows that the arginine form of p53 makes individuals seven times more susceptible to cervical carcinoma than the proline form. The p53 amino acid sequence commonly exists with either an arginine or a proline at position 72.
