Transmission: Infectious bronchitis is a very contagious poultry disease. It is spread by air, feed bags, infected dead birds, infected houses, and rodents. The virus can be egg-transmitted, however, affected embryos usually will not hatch.
Genotype-Definition: Genotype refers to the gene composition of an organism or cell for a given trait. Genotype is inherited through sexual reproduction and differs from phenotype. Phenotype refers to physical characteristics, such as height and color, that are expressed.An organism's genotype determines its phenotype.When the alleles for a given trait are homozygous, the genotype is identical.When the genotype is heterozygous, the alleles are different.henotype refers to physical characteristics, such as height and color, that are expressed. An organism's genotype determines its phenotype. When the alleles for a given trait are homozygous, the genotype is identical. When the genotype is heterozygous, the alleles are different.
The phenotype of an organism is the class to which that organism belongs as determined by the description of the physical and behavioral characteristics of the organism, for example its size and shape, its metabolic activities and its pattern of movement.he genotype is the descriptor of the genome which is the set of physical DNA molecules inherited from the organism's parents. The phenotype is the descriptor of the phenome, the manifest physical properties of the organism, its physiology, morphology and behavior.
