a) Mendel carried out an experiment to study the inheritance of two traits in garden pea because of the following:

  • traits are easily observable in peas,
  • the life cycle is short as compared to others,
  • a large number of offsprings and cross-pollination was easy as compared to others.

a) All progeny formed are phenotypically dominant but having heterozygous genotype.

c) The ratio of both genotype and phenotype obtained is 3:1, whereas:

  • F1 generation is monohybrid
  • F2 generation is monohybrid.
