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.
Genotype refers to the genetic traits in an organism. It has to do with the genetic coding of an organism. Such coding is inheritable. The genotype is the genetic load that is copied every time a cell divides, and therefore is inherited down to the next generation.he phenotype is a physical manifestation of the genotype, which means that it's what happens on the outside because an organism has the gene. An example of a â¦ phenotype would be if someone had blue eyes or something.
