TLDR
The genetic constitution of a population: Hardy-Weinberg equilibrium and changes in gene frequency: migration mutation, changes of variance, and heritability are studied.Abstract:
Part 1 Genetic constitution of a population: Hardy-Weinberg equilibrium. Part 2 Changes in gene frequency: migration mutation. Part 3 Small populations - changes in gene frequency under simplified conditions. Part 4 Small populations - less simplified conditions. Part 5 Small populations - pedigreed populations and close inbreeding. Part 6 Continuous variation. Part 7 Values and means. Part 8 Variance. Part 9 Resemblance between relatives. Part 10 Heritability. Part 11 Selection - the response and its prediction. Part 12 Selection - the results of experiments. Part 13 Selection - information from relatives. Part 14 Inbreeding and crossbreeding - changes of mean value. Part 15 Inbreeding and crossbreeding - changes of variance. Part 16 Inbreeding and crossbreeding - applications. Part 17 Scale. Part 18 Threshold characters. Part 19 Correlated characters. Part 20 Metric characters under natural selection.read more

Correlational selection on life history traits in the pitcher-plant mosquito
TL;DR: It is concluded that genetic architecture can have a significant, and quite asymmetrical and non-directional, effect on the response to correlational selection in the pitcher-plant mosquito, Wyeomyia smithii.

Correlation and Path Coefficient Analysis of Yield and Yield AssociatedTraits in Barley (Hordeum vulgare L.) Germplasm
TL;DR: Analyzing the extent of association between pairs of characters in genotypic and phenotypic levels and comparing the direct and indirect effects of the characters revealed that biological yield exerted maximum positive direct effect on grain yield across location followed by harvest index excluding Ofla.

TL;DR: The phenotypic correlation and principal component analysis showed that most of the traits evaluated are important for selection of high yielding genotypes and contributing their share for wider genetic variability of the genotypes, indicating the presence of enough variability for development of improved rice varieties.

Improvement of disease resistance by genetic methods
TL;DR: Populations of fish and shellfish show a wide variability in their ability to tolerate or resist infectious diseases, and quantitative genetic and animal breeding principles can be applied to produce populations with greater resistance or tolerance.

TL;DR: Examination of single nucleotide polymorphisms in bovine genes related to reproductive physiology provides further evidence to support the hypothesis that genetic variability is an important component of the number of antral follicles in the bovines ovary.
