Inheritance and variation of lint yield and fiber traits in a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton
The objective of this study was to evaluate a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton for two years. The traits that studied were lint yield per plant, lint %, fiber length, fiber strength and micronaire. A total of 31 cytogenetically stable lines (2n=4x=52) were produced from a cross between a G. barbadense line, Carnak and a G. hirsutumline, 4S,...
متن کاملHuman population expansion and microsatellite variation.
Polymorphisms at di-, tri-, and tetranucleotide microsatellite loci have been analyzed in 14 worldwide populations. A statistical index of population expansion, denoted S(k), is introduced to detect historical changes in population size using the variation at the microsatellites. The index takes the value 0 at equilibrium with constant population size and is positive or negative according to wh...
متن کاملPopulation Structure in a Comprehensive Genomic Data Set on Human Microsatellite Variation
Over the past two decades, microsatellite genotypes have provided the data for landmark studies of human population-genetic variation. However, the various microsatellite data sets have been prepared with different procedures and sets of markers, so that it has been difficult to synthesize available data for a comprehensive analysis. Here, we combine eight human population-genetic data sets at ...
متن کاملHuman population structure and its effects on sampling Y chromosome sequence variation.
The excess of rare variants in global sequencing studies of the nonrecombining portion of the Y chromosome (NRY) has been interpreted as evidence for the effects of human demographic expansion. However, many NRY polymorphisms are geographically localized and the effect of different geographical sampling on patterns of NRY variation is unknown. We use two sampling designs to detect population st...
متن کاملPopulation structure in Daphnia obtusa: quantitative genetic and allozymic variation.
Quantitative genetic analyses for body size and for life history characters within and among populations of Daphnia obtusa reveal substantial genetic variance at both hierarchical levels for all traits measured. Simultaneous allozymic analysis on the same population samples indicate a moderate degree of differentiation: GST = 0.28. No associations between electrophoretic genotype and phenotypic...
