Inbreeding depression—the reduced survival and fertility of offspring of related individuals—
occurs in wild animal and plant populations as well as in humans, indicating that genetic …

With the advent of rapid genotyping and next‐generation sequencing technologies, genome‐
wide association study (GWAS) has become a routine strategy for decoding genotype …

In any hybridization program, recognition of the best combination of two (or more) parental
genotypes to maximize variance within related breeding populations, and as a result the …

Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …

Whether inbreeding affects the demography and persistence of natural populations has
been questioned. However, new pedigree data from field populations and molecular and …

Key message Genetic atlas, reliable QTL and candidate genes of yield component traits in
wheat were figured out, laying concrete foundations for map-based gene cloning and …

Hybrids such as maize (Zea mays) or domestic dog (Canis lupus familiaris) grow bigger and
stronger than their parents. This is also true for allopolyploids such as wheat (Triticum spp.) …

Transgressive segregation and heterosis are the reasons that plant breeding works.
Molecular explanations for both phenomena have been suggested and play a contributing …

As populations become increasingly fragmented, managers are often faced with the
dilemma that intentional hybridization might save a population from inbreeding depression …

Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …
