Quantitative Genetic Assessment of Female Reproductive Traits in a Domesticated Pacific White Shrimp (Penaeus vannamei) Line in China

Scientific Reports, 2020
Seed production can be improved if genetic selection is applied to key reproductive traits when a substantial amount additive genetic variation is present that can be exploited in a selective breeding program.

The role of gene discovery, QTL analyses and gene expression in reproductive traits in the pig.

Society of Reproduction and Fertility supplement, 2020
The reproductive performance of the sow is one of the key factors affecting production profitability of the pig industry. Reproductive traits are in general, lowly heritable, and with reliable markers, they can be used to enhance current selection ...

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 Associated with Oxygen Consumption

Poultry Science, 1973
Abstract Hen-day production and hatchability of fertile eggs were investigated in high and low oxygen lines previously described by MacLaury and Johnson (Poultry Sci. 51: 591–597, 1972). After significant separation of the lines in 1965 both measures were significantly higher in the high oxygen line.

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

Postcopulatory sexual selection [PDF]

, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...
