detailed solution

Correct option is A

Mendel proposed the principles of inheritance, which are today referred to as ‘Mendel’s Laws of Inheritance’.Law of dominance - The dominant characters are expressed when factors are in heterozygous condition.Law of segregation - A recessive character that was not expressed in heterozygous condition may be expressed again when it becomes homozygous. Hence, characters segregate while formation of gametes.Law of independent assortment - When Mendel studied the inheritance of two characters together, it was found that the factors independently assort and combine in all permutations and combinations.
