Estimates of genetic and phenotypic parameters for reproductive traits in Iranian native Kordi sheep
The data set for estimation of genetic and phenotypic parameters of reproductive traits in Kordi sheep were collected from 1996 to 2013. The reproductive traits included age at first lambing (AFL), number of lambs born (NLB/EL) and weaned (NLW/EL) per ...

Complex social behaviour derived from maternal reproductive traits [PDF]
A fundamental goal of sociobiology is to explain how complex social behaviour evolves, especially in social insects, the exemplars of social living. Although still the subject of much controversy, recent theoretical explanations have focused on the evolutionary origins of worker behaviour (assistance from daughters that remain in the nest and help ...

Reproductive traits and economic aspects on dairy cattle. [PDF]
Abstract This study aimed to characterize the reproductive parameters and economic indicators of dairy farms. Data were from technical assistance of the Programa de Desenvolvimento em Pecuária Leiteira (PDPL-UFV) including 26 farms, from September 2022 to August 2023, comprising an entire production cycle.

Polymorphism of the prolactin gene and its association with reproductive traits in F2 local crossed chickens [PDF]
Background and Aim: Reproductive traits are crucial for genetic improvement in chickens. Prolactin (PRL) is a gene involved in a complex hormonal network that regulates reproduction in chickens.

Evolution of life cycles and reproductive traits: Insights from the brown algae
A vast diversity of types of life cycles exists in nature, and several theories have been advanced to explain how this diversity has evolved and how each type of life cycle is retained over evolutionary time.

Estimate of inbreeding depression on growth and reproductive traits in a Large White pig population
With the broad application of genomic information, SNP-based measures of estimating inbreeding have been widely used in animal breeding, especially based on runs of homozygosity.

Genetic differentiation and phenotypic plasticity jointly shape intraspecific trait variation, but their roles differ among traits. In short-lived plants, reproductive traits may be more genetically determined due to their impact on fitness, whereas ...

Reproductive trait differences drive offspring production in urban cavity‐nesting bees and wasps
The contrasting and idiosyncratic changes in biodiversity that have been documented across urbanization gradients call for a more mechanistic understanding of urban community assembly. The reproductive success of organisms in cities should underpin their
