The effect of synchronous and asynchronous egg transfer on foetal weight in mice selected for large and small body size.
The weight difference between large, small and unselected strains of mice were maintained when blastocysts of each genotype were transferred to unselected control recipients, suggesting that foetal genotype was an important factor in determining prenatal body size. The asynchronous transfer of large, small and unselected embryos resulted in a highly significant (P less than 0-001) elevation of ...
متن کاملDifferences in body compositions, growth and food intakes between mice which have been selected for a small and large body size.
1. Q-strain mice selected for high (QLF) or low (QSC) body-weight at 6 weeks of age were compared with respect to their body-weight increases, gross body compositions and food intakes. 2. DNA, RNA, protein and hydroxyproline contents were measured. 3. QLF animals were larger at all stages of development but ate more food and gained more body-weight per unit food intake with an apparently improv...
متن کاملEffect size – large, medium, and small
The overall purpose of the 'Statistical Points and Pitfalls' series is to help readers and researchers alike increase awareness of how to use statistics and why/how we fall into inappropriate choices or interpretations. We hope to help readers understand common misconceptions and give clear guidance on how to avoid common pitfalls by offering simple tips to improve your reporting of quantitativ...
متن کاملAtmospheric Hypoxia Limits Selection for Large Body Size in Insects
BACKGROUND The correlations between Phanerozoic atmospheric oxygen fluctuations and insect body size suggest that higher oxygen levels facilitate the evolution of larger size in insects. METHODS AND PRINCIPAL FINDINGS Testing this hypothesis we selected Drosophila melanogaster for large size in three oxygen atmospheric partial pressures (aPO(2)). Fly body sizes increased by 15% during 11 gene...
متن کاملIllusions of having small or large invisible bodies influence visual perception of object size
The size of our body influences the perceived size of the world so that objects appear larger to children than to adults. The mechanisms underlying this effect remain unclear. It has been difficult to dissociate visual rescaling of the external environment based on an individual's visible body from visual rescaling based on a central multisensory body representation. To differentiate these pote...
