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.
Phenotype. Definition. noun, plural: phenotypes. (1) The physical appearance or biochemical characteristic of an organism as a result of the interaction of its genotype and the environment. (2) The expression of a particular trait, for example, skin color, height, behavior, etc. , according to the individualâs genetic makeup and environment. Supplement. Phenotypes result from the expression of the genes of an organisms as well as the influence of environmental factors and random variation. The interaction between these factors have often been represented by the following relationship: genotype + environment + random variation â phenotype.
