Одной из центральных проблем в современном животноводстве остается поиск
генетических маркеров, которые упростили бы отбор и подбор животных для …

Reproductive modes of vertebrates are classified into two major embryonic nutritional types:
yolk deposits (ie, lecithotrophy) and maternal investment (ie, matrotrophy). Vitellogenin …

Viviparity is made possible by the placenta, a structure acquired relatively recently in the
evolutionary history of eutherian mammals. Compared to oviparity, it increases the survival …

Background Viviparity—live birth—is a complex and innovative mode of reproduction that
has evolved repeatedly across the vertebrate Tree of Life. Viviparous species exhibit …

Although most fishes are ectothermic, some, including tuna and billfish, achieve endothermy
through specialized heat producing tissues that are modified muscles. How these heat …

Environmental hypoxia challenges female reproductive physiology in placental mammals,
increasing rates of gestational complications. Adaptation to high elevation has limited many …

The search for genetic markers that simplify the selection of animals for crosses, increasing
the likelihood of offspring obtaining with the desired manifestation of economically valuable …

The transition from oviparity to viviparity has occurred independently over 150 times across
vertebrates, presenting one of the most compelling cases of phenotypic convergence …

The repeated emergence of the same trait (convergent evolution) in distinct species is an
interesting phenomenon and manifests visibly the power of natural selection. The underlying …

Determinism and contingency shape evolutionary trajectories and the extent to which
evolution is predictable depends on the relative contribution of each. However, the causes of …
