The branch of biology which deals with genes and inheritance patterns is called genetics. In these genetics, there are two types of genes. These genes are as follows:-

According to the question, the number of offspring in the cross is in the ratio of 3:1. It states that the number of offspring in the cross are more dominant than recessive.

According to the law of dominance, Mendel said that the dominant genes express always express themselves.

Therefore, the cross in the question is F2 generation.

The plants that were allowed to self pollinate were the F1 plants.

The plants that are true breeding are P generation plants.

The plants where there were 3times as many tall plants as short plants are in F2 generation.

This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants Pisum sativum to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.

He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.

As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.

As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
