1. ImplicaÃÃes do nÃmero de intercruzamentos nas propriedades genÃticas de uma populaÃÃo segregante de feijoeiro / Implications of the number of intercrossings in the genetic properties of a common bean population.
In autogamus species, like common bean na usual question about the breeding program based on hybridization, in the necessity to intercross plants of the F2 generation. The objective of this research was to verify the effect of 0, 1 and 2 intercrossings on the genetic properties of a common bean segregating population derived from multiple crossings. A involv

2. Genome-Wide High-Resolution Mapping by Recurrent Intermating Using Arabidopsis Thaliana as a Model
We demonstrate a method for developing populations suitable for genome-wide high-resolution genetic linkage mapping, by recurrent intermating among F(2) individuals derived from crosses between homozygous parents. Comparison of intermated progenies to F(2) and ``recombinant inbred'' (RI) populations from the same pedigree corroborate theoretical expectations

4. Single-locus heterotic effects and dominance by dominance interactions can adequately explain the genetic basis of heterosis in an elite rice hybrid
The genetic basis of heterosis of an elite rice hybrid was investigated by using an “immortalized F2” population produced by randomly permutated intermating of 240 recombinant inbred lines from a cross between the parents of Shanyou 63, the most widely cultivated hybrid in China. Measurements of heterosis for crosses in the immortalized F2 population wer

5. Polyandrous females discriminate against previous mates
In most animal species, particularly those in which females engage in polyandry, mate choice is a sequential process in which a female must choose to mate or not to mate with each male encountered. Although a number of theoretical and empirical investigations have examined the effects of sequential mate choice on the operation of sexual selection, how female
