|Genotype, phenotype and karyotype|
Genotype refers to the genetic make up of an organism. Generally the genes of an organism. The genotype of an organism can be represented as BB or Bb or bb based on the gene. If a person is having two recessive CFTR genes, then he will be getting cytic fibrosis. Genotype of an organism has also effect over the phenotype. Thus, genotype is representing the alleles of a gene in general. Genotyping is generally done based on PCR or hybridization.
Phenotype refers to the visible characters like structure, color and also the biochemical characters. This is based on the phenotype. Phenotyping can be done using biochemical assays.
Karyotype refers to the number of structure of chromosomes in an organism. karyotyping is done by staining and visualising the cells under microscope.
