Question

How do Mendel’s experiments show that traits are inherited independently?​

Answer 1

Answer:

Mendel crossed a pea plant having yellow coloured and rounded seeds with another pea plant having green coloured and wrinkled seed.

• The F1 generation has all round and yellow seeds.
• The F2 generation seeds are shown in the attachment. It can be seen from the diagram that all the characters are inherited independently. And the characters are: Round yellow, round green, wrinkled yellow, wrinkled green.

The phenotypic ratio is: 9:3:3:1

Following are the principles of inheritance that were developed based on Mendel’s experiments:

The fundamental theory of heredity:

According to the theory, offspring have their genes inherited from their parents.

Principle of segregation:

It was studied that during reproduction, the factors determining the traits get separated into reproductive cells, and this process is known as meiosis and reunites during fertilization.

Principle of independent assortment:

Different chromosomes have different genes located on them that can be inherited independently.

Therefore, the result of his experiment when he crossed a pea plant with yellow colour, round seed with green colour wrinkled seed were two parental and two recombinant phenotypes. The parental were yellow, round and green wrinkled. While the recombinant were yellow wrinkled and green round. This result explains that the traits are separate from their parental combinations and are inherited independently.
