The patterns of haplotype divergence at the mitochondrial gene cytochrome oxidase I (COI) found in this study suggest a postglacial western Europe and a eastern south-to-north colonization. Expand
Selection often overrides the effects of random processes in island populations of Philaenus spumarius (Homoptera)
The influence of various evolutionary factors on the populations of the colour polymorphic meadow spittlebug, Philaenus spumarius, was investigated on islands in the Gulf of Finland, and it is highly probable that the factor operating is meadow-specific selection. Expand
Chromosome banding pattern in a polymorphic population of Sorex araneus from northeastern Finland.
The banding pattern of race C is presented and proposed as a basis for comparisons between chromosomal races of Sorex araneus and polymorphism was slightly more restricted than in another race C population investigated by Fredga. Expand
RECOMBINATION IN SIX HOMOPTEROUS FAMILIES
- O. Halkka
- 1 March 1964
This paper is primarily an attempt to compare recombination indices in the different families of an insect group, and an estimate of the degree of chiasma localization in both sexes is necessary. Expand
The founder principle, founder selection, and evolutionary divergence and convergence in natural populations of Philaenus.
Parts of the archipelago of the Baltic Sea are rising above the water level at a steady, slow rate, and an early stage and a late stage can be distinguished in the development of meadows on the islands, which can be said to go through a divergence phase followed by a convergence phase. Expand
Color Polymorphism in Some North American Philaenus spumarius (Homoptera: Aphrophoridae) Populations
North American Philaenus spumarius populations exhibit a range of color forms comparable to those found in Europe and Asia, and the prevailing modes of polymorphic balance are unique in the sense that similar modes have not been encountered in Europe or Asia. Expand
The genetic basis of balanced polymorphism in Philaenus (Homoptera)
Evidence is presented for the hypothesis, here advanced explicitly for the first time, that the colour genes are components of supergenes, and certain assumptions are made to support the hypothesis that alleles high in the dominance hierarchy are of more recent origin than alleles at or near the bottom.
