This chapter outlines some of the basic principles in genetics and attempts to illustrate the link between genes and the performance of individual farm animals, or populations of them.

This chapter focuses on the use of genomic information to characterize forest tree population diversity, the relationship among populations, and the detection of loci that contribute to their adaptation. Other aspects related to population genetics of tree species, such as geographic variation,...

This chapter discusses the quantitative genomics of forest tree breeding. The collective analysis of large numbers of variable loci in individuals of breeding populations is now feasible for several species, and is bound to become an essential tool to advance genetic gains in future tree breeding...

This book chapter discusses the key factors such as genomics, RD1-RD3 loci, cell envelope, secretory systems, PE/PPE genes, regulatory genes, PhoPR regulatory systems, and RskA-Slg regulon genes that contribute to the virulence of Mycobacterium bovis which enable the mycobacterium to survive and...

This chapter provides the guidelines for standard genetic nomenclature to facilitate comparison of results between experiments and prevent confusion. Focus is given on locus and gene names and symbols as well as trait and phenotype terminology.

In this chapter, best linear unbiased prediction's (BLUP) theoretical background is briefly presented, considering a univariate animal model, and its application to several univariate models in genetic evaluation is illustrated. Constructing the mixed model equations, progeny (daughter) yield...

With approximately 124 described species of Phytophthora, reliance on morphological characteristics for species identification is challenging, even for experienced researchers. While DNA sequence-based approaches are the most accurate for species identification, gel-based techniques can also be...

KIT mutations play a key role in producing white spotting patterns in horses. However, not all white spotting patterns in horses are products of the KIT locus. The next few chapters describe the genetics of the traits gray, overo, splashed white and leopard, all of which are encoded by genes...

This chapter describes the genetics of parentage testing by using DNA tests, polymerase chain reaction and microsatellite markers. An example and future applications of genetic testing are also included.

In evaluating evidence from genome-wide association studies (GWAS) of unrelated subjects, analysts must take care to avoid confounding by differences in allelic frequency that are associated with the trait for reasons other than a direct genetic influence, termed population stratification. "Global" ...
