Developmental stability in stocks of White Leghorn chickens.
The degree of asymmetry in bilateral morphological characters may reflect genetic and environmental stressors. Shank length and diameter, weight and length of the first primary wing feather, and distance between the junction of upper and lower mandibles and auditory canal (face length) were used to classify bilateral types and measure relative asymmetry (RA) in six genetic stocks. The stocks we...
متن کاملEarly exposure to the opposite sex affects mating behaviour in White Leghorn chickens
To examine the effect of early exposure to the opposite sex on mating behaviour in White Leghorns we observed interactions between males and females that had been raised with (mixed-sex) or without (same-sex) the other sex. Groups of six females and one male were assigned to one of four treatments based on how they were raised: mixed-sex females with a mixed-sex male (MM), same-sex females with...
متن کاملViruses from extreme thermal environments.
Viruses of extreme thermophiles are of great interest because they serve as model systems for understanding the biochemistry and molecular biology required for life at high temperatures. In this work, we report the discovery, isolation, and preliminary characterization of viruses and virus-like particles from extreme thermal acidic environments (70-92 degrees C, pH 1.0-4.5) found in Yellowstone...
متن کاملResponse of white leghorn chickens of various genetic lines to infection with avian leukosis virus subgroup J.
In Experiment 1, chickens from various white leghorn experimental lines were inoculated with strain ADOL-Hcl of subgroup J avian leukosis virus (ALV-J) either as embryos or at 1 day of age. At various ages, chickens were tested for ALV-J induced viremia, antibody, and packed cell volume (PCV). Also, at 4 and 10 wk of age, bursal tissues were examined for avian leukosis virus (ALV)-induced prene...
متن کاملTissue tropism and bursal transformation ability of subgroup J avian leukosis virus in White Leghorn chickens.
In Experiment 1, a monoclonal antibody against the envelope glycoprotein (gp85) of subgroup J avian leukosis virus (ALV-J) was used to study the distribution of ALV-J in various tissues of White Leghorn chickens inoculated as embryos with the strain ADOL-Hcl of ALV-J. At 2 and 6 wk of age, various tissues from infected and control uninfected chickens were tested for the presence of ALV-J gp85 b...
