Question

What do you understand by a phenotype and a genotype? Explain by giving an example.

Answer 1

Genotype. The gene complement or genetic constitution of an individual with regard to one or more characters irrespective of whether the genes are expressed or not. For example, the genotype of hybrid tall Pea plant is Tt, pure tall TT and dwarf tt.
Phenotype Is observable or measurable distinctive structural or functional characteristic of an individual with regard to one or more characters which is a result of result of gene products brought to expression in a given environment. For recessive genes, the phenotype is similar to genotype. For dominant genes, the phenotypic expression can be due to its homozygous genotype or heterozygous genotype. For example, phenotypic tall pea plant can be genotypically TT or Tt.
