Allometry Between Vegetative and Reproductive Traits in Orchids [PDF]
Frontiers in Plant Science, 2021 In flowering plants, inflorescence characteristics influence both seed set and pollen contribution, while inflorescence and peduncle size can be correlated with biomass allocation to reproductive organs. Peduncles also play a role in water and nutrient supply of flowers, and mechanical support.

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.

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.

An Assessment of the Genetic Parameters of Boars’ Reproductive Traits
Genes, 2023 The aim of this study was to estimate genetic parameters for the reproductive traits of boars based on single-nucleotide polymorphism data. A total of 109,836 semen samples from 2249 boars were collected between 2010 and 2022. Five basic traits were assessed: sperm volume, sperm concentration, motility, number of abnormal sperm, and, for the first time

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 ...

Reproductive efficiency and milk yield in Sindhi breed cattle
Brazilian Journal of Veterinary Medicine, 2022 The aim of this study was to identify the average of productive and reproductive traits in Red Sindhi females and evaluate if there is an influence of the reproductive traits on milk yield in this breed. Data related to reproductive and productive traits
