We assess the effect of this variation on nesting success and egg success. Yolk represented 29.5% of egg mass whereas albumen was 63.9%. Yolk mass increased with egg width but not with egg length, while mass of albumen increased mainly with egg length. The largest and smallest eggs were ...
The energetic cost of growth and tissue maintenance did not differ significantly. It is concluded that,10 + 9 among chicken eggs of different sizes, 1) the growth rate of the embryo relates to the size of its egg, probably genetically and because of differences in water content, 2) ...
However, recent experiments found that the size of the mitotic spindle scales with the cell size only in small cells, but approaches an upper limit (about 60 μm) in large cells during the early embryogenesis of Xenopus laevi eggs4. Similar phenomena can be recapitulated by in vitro ...

It is concluded that the clutch size of these Eudyptes penguins is invariably two eggs, that one-egg clutches are usually reported because the loss of the A egg was not noticed and that most three-egg clutches are the result of adoption of eggs....
