WASHINGTON (AP) — Two-thirds of animal and plant populations are declining in genetic diversity, which makes it harder to adapt to environmental changes, according to research published Wednesday.

Copy number variations (CNVs) are a pervasive form of genomic variation that entail duplications or deletions of DNA segments ranging from kilobases to megabases. In animal genomes, CNVs contribute ...

Pure-bred dogs have been regarded as superior to crossbreeds or what some people refer to as mutts. However, we now understand that producing purebred dogs has drawbacks. The lack of variety in the ...
