Question
How did Mendel’s experiments show that different traits are inherited independently? Explain.
✓
Answer
Mendel carried out dihybrid crosses by crossing two pea plants differing in contrasting traits of two characters. For example he crossed a pea plant having yellow coloured and round seed with another pea plant bearing green coloured and wrinkled seed. In the $F_2$ generation, he got the pea plants with two parental and two recombinant phenotypes as yellow round and green wrinkled (parental) and yellow wrinkled and green round (recombinant). This indicated that traits separated from their original parental combinations and got inherited independently.
