The primary motivation behind breeding dogs should be the desire to improve the breed. The breeder should be passionate about advancing the breed's characteristics, health, and well-being. Can you describe your objective in breeding a litter of dogs? The goal of breeding a litter of dogs shoul...
You must start with good sound stock and learn as much as possible about it. Only the offspring are the proof of what you can learn. The longer you inbreed, the more alike the offspring will become, but don't hesitate to eliminate from your breeding program those dogs or bitches that th...

Non-cyclic rodent outbreaks are predominantly driven by an elevation of reproductive rates some 6–9 months preceding a population outbreak. The conditions that trigger this atypical breeding pattern vary depending on the rodent species and the ecosystem. Nevertheless, species that have population outbrea...
Although the role of retinal glial cells in retinal neovascularization has been a focus of recent studies, relatively less is known about the contribution of myeloid cells to this abnormality. The late stage of DR, also called proliferative DR, involves pathological angiogenesis and the formation of...

2/ It apparently has some effect on breeding because it is going extinct (maybe it causes sexual/reproductive dysfunction in some way.) The Evotard fairy of positive selection must have died millions of years ago, because it is not being selected. ...

so we started breeding grains with a sweet tooth. (And Japan, one of the main reasons we had built the bomb factories in the first place, kindly “donated” some important fertilizer-intensive crop varieties — including a type of wheat that later became the basis of the “Green Revolution...
Evolution is driven by interactions between genetics and nature, and the Earth's rock layers preserve a record of this process. By studying fossilized remains, scientists can learn about how modern animals evolved. But how these animals came to live where they live, look the way t...
