This paper presents the 12th update of the human obesity gene map, which incorporates
published results up to the end of October 2005. Evidence from single‐gene mutation …

Epigenetic inheritance plays a crucial role in many biological processes, such as gene
expression in early embryo development, imprinting and the silencing of transposons. It has …

Methods for mapping QTL are actively used in the chicken to identify chromosomal regions
contributing to variation in traits related to growth, disease resistance, egg production …

Differences in relative fitness of male and female offspring across ecological and social
environments should favour the evolution of sex-determining mechanisms that enable …

Egg-laying performance reflects the overall reproductive performance of breeding hens. The
genetic traits for egg-laying performance have low or medium heritability, and, depending on …

This study was designed to perform an association analysis and identify SNP markers
associated with production traits of Japanese quail using restriction-site-associated DNA …

Maternal hormones in the yolk of birds' eggs have been a focus of attention in behavioral
and evolutionary ecology stimulated by the pioneering work of Hubert Schwabl. Since then …

Background Feed contributes to over 60% of the total production costs in the poultry
industry. Increasing feed costs prompt geneticists to include feed intake and efficiency as …

Little is known about epigenetic mechanisms in birds with the exception of the phenomenon
of dosage compensation of sex chromosomes, although such mechanisms could be …

The review addresses the fundamental process of 'imprinting'. In his classical studies on
newly hatched goslings Konrad Lorenz analysed the development of social binding and …
