Avian genetic diversity: Domesticated species
GENETIC DIVERSITY IS CONSIDERED crucial to the continued survival of a species, be it wild or domestic. Such within-species diversity has been the raw material of agriculturists over millennia. In response to selective breeding and the differential survival of less fit animals, preferred traits have been accentuated and clustered to produce distinct breeds and varieties of the modern domesticat...
متن کاملGermline Modification and Engineering in Avian Species
Production of genome-edited animals using germline-competent cells and genetic modification tools has provided opportunities for investigation of biological mechanisms in various organisms. The recently reported programmed genome editing technology that can induce gene modification at a target locus in an efficient and precise manner facilitates establishment of animal models. In this regard, t...
متن کاملAspergillosis in Avian Species: A Review
Accepted: 19/02/2015 Abstract Aspergillosis is an infectious, non-contagious fungal disease of wild and domestic birds caused by fungus Aspergillus species. It is characterized by primary involvement of respiratory tract, formation of yellow cheesy plaques and hard nodular masses in the lungs and air sacs, though other organs may also be generally involved. This fungal disease is of economic im...
متن کاملSong variation in an avian ring species.
Divergence of mating signals can occur rapidly and be of prime importance in causing reproductive isolation and speciation. A ring species, in which two reproductively isolated taxa are connected by a chain of intergrading populations, provides a rare opportunity to use spatial variation to reconstruct the history of divergence. I use geographic variation in the song of a likely ring species, t...
متن کاملSerotyping of avian mycoplasma species in India.
Two-hundred and two strains of avian mycoplasma species belonging to 10 biotypes were typed serologically by employing disk growth inhibition (DGI) and indirect hemagglutination (IHA) tests. These could be placed into seven serotypes, namely A (80), B (50), C (3), E (34), L (13), P (4), and 1 and R (18). The figures in parentheses show the number of strains within each type. A close relationshi...
