An analysis of selection on a colour polymorphism in the northern leopard frog.
In this study, we investigated the role of selection in the maintenance of a dorsal colour polymorphism in natural populations of the northern leopard frog, Rana pipiens. We determined genetic structure both spatially and temporally from a suite of putatively neutral molecular markers and tested whether or not the colour locus exhibited patterns of genetic variation that differed from those of ...
متن کاملPopulation genetics of polymorphism and divergence under fluctuating selection.
Current methods for detecting fluctuating selection require time series data on genotype frequencies. Here, we propose an alternative approach that makes use of DNA polymorphism data from a sample of individuals collected at a single point in time. Our method uses classical diffusion approximations to model temporal fluctuations in the selection coefficients to find the expected distribution of...
متن کاملMechanism of Pollution Control for Aquatic Plant Water Hyacinth
The aquatic plant water hyacinth is a powerful tool for mediating pollution from aquatic environment. PM3 semiempirical method and FTIR spectroscopy was used to predicate the mechanism of pollution control. First the plant is subjected to acetic acid 0.1 M for 19 hours. FTIR proves that the plant is cellulose like material. Furthermore, the acetylated plant is looks like cellulose acetate. The ...
