Experimental crosses between Mepraia gajardoi and M. spinolai and hybrid chromosome analyses reveal the occurrence of several isolation mechanisms.

Infection, Genetics and Evolution, 2016
Hematophagous insects of the subfamily Triatominae include several species with a large variety of shapes, behavior and distribution. They have great epidemiological importance since most of them transmit the flagellated protozoan Trypanosoma cruzi, the ...

Haplotyping a quantitative trait with a high-density map in experimental crosses. [PDF]

PLoS ONE, 2007
BACKGROUND: The ultimate goal of genetic mapping of quantitative trait loci (QTL) is the positional cloning of genes involved in any agriculturally or medically important phenotype.

Cytogenetic and morphologic approaches of hybrids from experimental crosses between Triatoma lenti Sherlock & Serafim, 1967 and T. sherlocki Papa et al., 2002 (Hemiptera: Reduviidae).

Infection, Genetics and Evolution, 2014
The reproductive capacity between Triatoma lenti and Triatoma sherlocki was observed in order to verify the fertility and viability of the offspring. Cytogenetic, morphological and morphometric approaches were used to analyze the differences that were ...

Genomic and environmental selection patterns in two distinct lettuce crop-wild hybrid crosses [PDF]

, 2013
Genomic selection patterns and hybrid performance influence the chance that crop (trans)genes can spread to wild relatives. We measured fitness(-related) traits in two different field environments employing two different crop–wild crosses of lettuce.

Performance of maize single-crosses developed from populations improved by a modified reciprocal recurrent selection Performance de híbridos simples de milho desenvolvidos de populações melhoradas por seleção recorrente recíproca modificada

Scientia Agricola, 2010
Maize (Zea mays L.) elite inbred lines developed from pedigree programs tend to be genetically related. Therefore, it is necessary to incorporate unrelated inbreds to those programs to allow the continued release of outstanding single-crosses.
