On the presence of DNA polymerase alpha in human lymphocyte nuclei and chromosomes.

abstract：:Chromosome polymorphism in Drosophila buzzatii is under selection but the genes responsible for the effect of the inversions of fitness are unknown. On the other hand, there is evidence for selection on several allozyme loci but the presence of paracentric inversions on the second chromosome, where most of the polymor...

abstract：:Heterozygotes are assumed to mate with a frequency that is any general function, f(v), of their population frequency, v. Models are analysed in which the selection that determines the function f(v) acts either on one sex alone or on both sexes equally. The central equilibrium point v* = 1/2 always exists; it is stable...
