Mitochondrial DNA variation within and between two species of neotropical Anopheline mosquitoes (Diptera: Culicidae)

Article Abstract:

Restriction site analysis was done to study variations in mitochondrial DNA (mtDNA) in Anopheles rangeli and A. trinkae, two neotropical mosquitoes collected from different parts of Latin America. The results showed a higher maternal gene flow and lower divergence in A. trinkae compared to that of A. rangeli. Such findings are thought to be due to either A. trinkae's distinctive matrilineal history or its considerably restricted geographic range along the eastern flank of the Andes.

Brown larva: an allele of the green larva mutation in the malaria mosquito, Anopheles stephensi

Article Abstract:

A study is conducted to examine pigment mutation in Anopheles stephensi obtained from Bangalore, India. The study analyzes the effects of crossing between green and brown larvae with wild-type mosquitos. The study has found that the larva is brown throughout except at the eyes, which are black. The crosses determine the allelism among the types with wild-type dominant followed by green then brown. The mutation is an autosomal recessive.

Microphthalmia cloudy-eye (mi (super ce)): a new murine allele

Article Abstract:

Genetic profile analysis reveals that a new mutation rather than genetic contamination leads to the phenotype of white, pink-eyed mouse among DBA/2N mice. This phenotype exhibits pleiotropic effects. They include white color due to the absence of melanocytes, small malformed eyes with reduced pigment in retina, choroid and iris, abnormally thin stria vascularis of the inner ear, and reproductive defects in females.
