Inferences of Mendel:

  • A trait is controlled by the combination of two traits.
  • One character is expressed (dominant character) and the other character remains hidden (recessive character) in the offspring first generation.
  • The character which remains hidden in the first generation appears in the second generation.
  • The ratio of the dominant character and recessive character in the second generation is 3:1

Gene – Allele: The gene present in the chromosome of the nucleus determines the character. A gene that controls a trait has different forms. The different forms of a gene are called alleles. Generally, a gene has two alleles. When. we illustrate hybridization experiment, the allele that controls the dominant character that is expressed in the first generation is indicated by a capital letter and the allele that controls recessive character is indicated by a small letter.
