C YTOLOGICAL studies of natural populations are revealing an increasing number of species, both plant and animal, whose populations are characterized by polymorphism for chromosomal rearrangements. Recent examples, for instance, have been found in the marine snail Purpura lapillus by STAIGER (1954), in the grasshopper Moraba scurra by WHITE (1956), in two species of cockmaches (LEWIS and JOHN 1957; JOHN and LEWIS 1958,1959), and in several species of the genus Clarkia (refs. in LEWIS and LEWIS… 

Figures and Tables from this paper

Intraspecific hybridization and its bearing on chromosome evolution inVicia narbonensis (Fabaceae)
TLDR
The present results provide probably the first example indicating that interchange homozygosity (A) is not only firmly established but also has enabled the species to spread further by adapting to a wide range of habitats.
CYTOGENETIC STUDIES IN CLARKIA, SECTION PRIMIGENIA. IV. A CYTOLOGICAL SURVEY OF CLARKIA GRACILIS
TLDR
Cytological differences, coupled with differences in morphology, ecology, and distribution indicate that C. gracilis should be subdivided into four subspecies instead of the three presently recognized.
Meiosis in translocation heterozygotes in the mosquito Culex pipiens
TLDR
From a total of 120 lines that showed a certain amount of sterility 12 lines were studied cytologically, and 10 lines showed reciprocal chromosome exchanges at late pachytene and diplotene cross configurations with large asynaptic regions at the center of the cross are obligatory.
Origin of reciprocal translocations and their effect in Clarkia speciosa
TLDR
The frequency of chromosomal nondisjunction (adjacent segregation) was found to be positively correlated with the number of chromosomes in the translocation multiple and had little affect on fertility whereas the largest multiples of 16 chromosomes had an average disjunction of about 10% and correspondingly low fertility.
Quantitative studies on mating systems
TLDR
The purpose of this investigation is to study in detail the mating systems involved in certain artificial populations of Jima beans, Phaseolus lunatus, and to investigate the randomness of observed outcrossing and possible trends in such cases where outCrossing appears non-random.
Quantitative studies on the mating system of jute (Corchorus olitorius L.)
TLDR
The propensity to outcross was not a simple function of changing gene frequency but was associated with the genotype of individual selected, and nonrandomness was also independent of flowering dates.

TLDR
The hypothesis is postulate, that segregation of the chromosomes involved in a translocation is under strict genetic control, attributable to a single, Mendelian factor, called "sg", which exists in a series of multiple alleles causing different relations between alternate and adjacent segregation.
Determinants of outcrossing rate in a predominantly self-fertilizing weed, Datura stramonium (Solanaceae)
TLDR
The strong effect of floral morphology suggests that the very low population-wide levels of outcrossing in D. stramonium may represent a persistent mixing mating system rather than a transition to complete selfing.
Quantitative studies on mating systems
TLDR
Evidence has been accumulating which suggests that many plant species have genetically variable mating systems and the mathematical consequences of such a mating system have been examined.
Inheritance and distribution of trichome phenotypes in Datura wrightii
TLDR
It is hypothesize that feeding by herbivorous insects and/or water stress may play a role in maintaining this polymorphism in natural plant populations.

Selection for Interchange Heterozygosity in an Inbred Culture of Blaberus Discoidalis (Serville).
TLDR
The authors have recently described wild and laboratory populations of the American cockroach (Periplaneta americana) where interchange heterozygotes are at a selective advantage and the genetic and structural preadaptations are favourable, the latter of which can account for their selective superiority in certain populations.
THE RELATION OF AN INVERSION SYSTEM TO RECOMBINATION IN WILD POPULATIONS
TLDR
The inversions of Drosophila pseudoobscura, which are proposed to discuss, are confined chiefly to two chromosomes, the acrocentric third and the metacentric X and, in the latter, to its right arm.
CHROMOSOME END ARRANGEMENTS IN DATURA INOXIA, D. METELOIDES AND D. METEL'
TLDR
The method for chromosome analysis used in the present studies is the same which has been developed by Bergner and Blakeslee in a series of chromosome investigations and is based on Belling's observation that like ends of homologous chromosome are mutually attracted and on his hypothesis of segmental interchanges between non-homologous chromosomes.
An Analysis of Data from Laboratory Populations of Drosophila Melanogaster.
TLDR
One of the most commonly applied tests for heterosis, a statistical test for an excess of heterozygotes in a population, is actually ambiguous even if the data should consist of a large number of repiicated trials or observations.
Plant breeding studies in leguminous forage crops I. Natural cross-breeding in winter beans
TLDR
When the above expressions are applied to a case in winter beans, in which the parent plants were selected for high yield it is found that the different estimates of p agree, but those of f do not.
