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 AND GENOTYPE. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related.HENOTYPE AND GENOTYPE.
