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.
It's a genotype. The 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. The genotype is the two-letter abbreviation thingy. Genotype means the ge â¦ netic constitution of the organism. The genotype results in the phenotype.   A genotype is the actual composition of the alleles present on each chromosome for a particular gene in an organism. A phenotype is the observed trait in the organism.
