Answer:

See the answer below

Step-by-step explanation:

Mendel's second law of genetics is also known as the law of independent assortment of genes.

In this law, Mendel opined that genes are independently inherited. In other words, Mendel said that the factors that dictate the physical attributes of living organisms are inherited independently.

This means, for example, that the color of your eyes is independently inherited from the color of your skin, your skin color is independent of your hair color, etc.

Mendel was able to prove this law by performing a dihybrid cross using the pea plant.

A true-breeding plant that is dominant for round and yellow traits (RRYY) was crossed with another true-breeding plant that is recessive for wrinkled and green traits (rryy).

All the F1 offspring were round with yellow color and the cross was advanced to F2. The F2 plants segregated in the ratio of 3:1 for the round trait to wrinkled traits and also 3:1 for the yellow to green traits respectively.

The outcome was the same as carrying out a monohybrid cross for each trait independently. Hence, Mendel concluded that traits are inherited independently of each other.
