Gene flow and population differentiation.
TL;DR: The results of experimental and theoretical models show that it is possible for local differentiation to evolve parapatrically in spite of considerable gene flow if the selection gradients are relatively uniform, andGene flow may be unimportant in the differentiation of populations along environmental gradients.

B-Chromosome Systems in Flowering Plants and Animal Species
TL;DR: This chapter discusses the B-chromosome systems in flowering plants and animal species, which are completely stable during the cell cycle and are inherited in a constant and unchanging form along with the A chromosomes.

CHAPTER 4 – B Chromosomes
TL;DR: In this paper, it was shown that supernumerary chromosomes are common features in many eukaryotic genomes, making a resolution of these issues an integral aspect of genome biology.

Ecotypic differentiation in the grasshopper Chorthippus brunneus : life history varies in relation to climate
Mark G. Telfer,Mark Hassall +1 more
TL;DR: Evidence from regression analysis supports the hypothesis that ecotypic differentiation in C. brunneus is an evolutionary response to Climatic variation, and the existence of intraspecific genetic diversity for climatic adaptations has implications for biodiversity conservation and the understanding of biotic responses to climatic change.
Journal ArticleDOI
B chromosome ancestry revealed by histone genes in the migratory locust.
TL;DR: Strong evidence for B chromosome ancestry in the migratory locust is provided, based on the location of genes for the H3 and H4 histones in the B chromosome and a single A chromosome pair, showing the B-chromosome ability to persist in natural populations for long periods of time.
