Reproductive Traits: Evidence for Sexually Selected Sperm [PDF]

Current Biology, 2008
Sperm exhibit extraordinary morphological divergence yet precise evolutionary causes often remain elusive. A quantitative genetic study sheds light on the major role postcopulatory sexual selection could play in determining sperm size.

Evidence for reproductive senescence across ray-finned fishes: A review

Frontiers in Ecology and Evolution, 2022
The origin, incidence, and consequences of reproductive senescence vary greatly across the tree of life. In vertebrates, research on reproductive senescence has been mainly focused on mammals and birds, demonstrating that its variation is largely linked ...

Sex-limited chromosomes and non-reproductive traits

BMC Biology, 2022
AbstractSex chromosomes are typically viewed as having originated from a pair of autosomes, and differentiated as the sex-limited chromosome (e.g. Y) has degenerated by losing most genes through cessation of recombination. While often thought that degenerated sex-limited chromosomes primarily affect traits involved in sex determination and sex cell ...

A novel association between hemoglobin subunit beta gene and reproductive performance in Awassi ewes

Journal of the Saudi Society of Agricultural Sciences, 2022
This study was performed to assess the polymorphism in the HBB gene and its association with reproductive traits in Awassi ewes. Genomic DNA extracted from 124 and 100 Awassi ewes, respectively, produced single and twins.

Genetic Control of Reproductive Traits in Tomatoes Under High Temperature

Frontiers in Plant Science, 2020
Global climate change is increasing the range of temperatures that crop plants must face during their life cycle, giving negative effects to yields. In this changing scenario, understanding the genetic control of plant responses to a range of increasing ...

Complex Reproductive Traits and Whole-Organism Performance [PDF]

Integrative and Comparative Biology, 2017
Arnold's 1983 path-analytic paradigm, considering "morphology, performance, and fitness," has been elaborated in several ways. For example, current versions recognize the level of "behavior" (including aspects of motivation) as a filter between performance abilities (only measurable if motivation is maximal) and fitness components.

Genetic Relationship of Body Energy and Blood Metabolites with Reproduction in Holstein Cows [PDF]

, 2008
Body condition score (BCS), energy content (EC), cumulative effective energy balance (CEEB), and blood serum concentrations of glucose, beta-hydroxybutyrate (BHBA), and nonesterified fatty acids ( NEFA) were measured throughout first lactation in 497 ...
