Question
What are the main generalizations given after Mendel’s experiments on the pea plant?
✓

Answer

After the Mendel’s laws of inheritance and his experiments, following generalizations were made:

  1. Single trait is shown due to single gene. Every single gene has two contrasting alleles.
  2. Two alleles are always in interaction in which one is completely dominant while other is completely recessive.
  3. Factors which were later called genes for different traits are always present on different chromosomes. These traits can assort independently of each other.
