Sex differences in tendon structure and function [PDF]
Journal of Orthopaedic Research, 2017 ABSTRACTTendons play a critical role in the transmission of forces between muscles and bones, and chronic tendon injuries and diseases are among the leading causes of musculoskeletal disability. Little is known about sex‐based differences in tendon structure and function. Our objective was to evaluate the mechanical properties, biochemical composition,

Sex Differences in Human Brain Structure at Birth
Biology of Sex DifferencesBackground Sex differences in human brain anatomy have been well-documented, though remain significantly underexplored during early development. The neonatal period is a critical stage for brain development and can provide key insights into the role that

Sex structure of hemp convergent hybrids
Agrobiologia, 2021 Inbreeding and its extreme form (self-pollination) are an effective method for stabilizing the monoecious traits of industrial hemp. The hybrids with self-pollinated lines as the components of which, in most cases, were characterized by a better sex ...

Optimal Sex Ratios in Structured Populations [PDF]
Journal of Theoretical Biology, 2000 In this paper, we develop a general method to determine evolutionary equilibrium sex ratios and to check evolutionary stability, continuous stability and invadability in exact genetic models with or without dominance. This method is then applied to three kinds of models for structured populations: the first one concerns Hamilton's LMC model, except ...
