Stayability in the Era of Early-Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits. [PDF]

J Anim Breed Genet
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

Evo-devo of human adolescence: beyond disease models of early puberty [PDF]

, 2013
Despite substantial heritability in pubertal development, much variation remains to be explained, leaving room for the influence of environmental factors to adjust its phenotypic trajectory in the service of fitness goals.

Screening for Mutations of 21-Hydroxylase Gene in Hungarian Patients with Congenital Adrenal Hyperplasia [PDF]

, 1999
Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders, causing impaired secretion of cortisol and aldosterone from the adrenal cortex, with subsequent overproduction of adrenal androgens.

Alternative adjustment of scrotal circumference for growth traits in Nellore cattle

Revista Brasileira de Zootecnia, 2020
The objective of this study was to estimate adjustment factors of scrotal circumference for growth traits in Nellore cattle. Measurement at post-yearling of scrotal circumference from 100,107 Nellore was adjusted for six traits: age (A), body weight (BW),

Tissue expression profiles unveil the gene interaction of hepatopancreas, eyestalk, and ovary in the precocious female Chinese mitten crab, Eriocheir sinensis

BMC Genetics, 2019
Background Sexual precocity is a common biological phenomenon in animal species. A large number of precocity individuals were identified in Chinese mitten crab Eriocheir sinensis, which caused huge economic loss annually.
