GENETIC ANALYSIS OF MEANS AND PHENOTYPIC VARIANCES FOR GRAIN YIELD AND SEVERAL TRAITS IN SEVERAL GENERATIONS FOR TWO CROSSES OF BARLEY [PDF]
Genetic analysis of means and phenotypic variances for grain yield and several traits in five generation (P1,P2,F2,F3, and F4) for to crosses of a six row barley , Hordeum vulgare L.(Gezera-1 x Benedict and Baraka x Arivate) were carried out to estimate:

THE APPLICATION OF DISCRETE HIDDEN MARKOV MODEL ON CROSSES OF DIPLOID PLANT
The hidden Markov model consists of a pair of an unobserved Markov chain {Xk} and an observation process {Yk}. In this research, the crosses of diploid plant apply the model.

Cross-border genetic testing [PDF]
As genetic testing (GT) is now available for many rare disorders, no GT laboratory can be expert enough to provide every test. Samples are therefore sent between laboratories for testing, often across borders. Such cross-border testing raises some questions: The 2003 OECD survey of 827 molecular GT laboratories in 18 countries found that 64% of ...

Multi-trait Improvement by Predicting Genetic Correlations in Breeding Crosses
The many quantitative traits of interest to plant breeders are often genetically correlated, which can complicate progress from selection. Improving multiple traits may be enhanced by identifying parent combinations – an important breeding step – that ...

GenomeMixer: a complex genetic cross simulator [PDF]
Abstract Summary: GenomeMixer is a cross-platform application that simulates meiotic recombination events for large and complex multigenerational genetic crosses among sexually reproducing diploid species and outputs simulated progeny to several standard mapping programs.

Breeding exploits the phenomenon of heterosis for an improved productivity, but negative effects reduce heterosis in wide crosses. The genetics underlying heterosis, the difference in performance of crosses compared with midparents, is hypothesized to ...

Genetic draft and valley crossing [PDF]
ABSTRACTLiving systems are characterized by complex adaptations which require multiple coordinated mutations in order to function. Empirical studies of fitness landscapes that result from the many possible mutations in a gene region reveal many fitness peaks and valleys that connect them.

Genetic parameters in intra-gene and inter-gene pool crosses of common bean (Phaseolus vulgaris L.) for root distribution [PDF]
The knowledge about the genetic behavior of roots can be the solution to the main climatic problems and the key for increased production of agricultural crops.

In flowering plants, F1 hybrid seed lethality is a common outcome of crosses between closely related diploid species, but the genetic basis of this early-acting and potentially widespread form of postzygotic reproductive isolation is largely unknown.

The effects of disruptive and stabilizing selection on body size in Drosophila melanogaster. III. Genetic analysis of two lines with different reactions to disruptive selection with mating of opposite extremes [PDF]
A genetic analysis was made of two lines which when subjected to disruptive selection with compulsary mating of opposite extremes (D−) showed a different response viz.
