How do Mendel’s experiments show that traits may be dominant or recessive ?

Option B

Option C

Option D

Solution

Mendel selected true breeding tall $(TT)$ and dwarf $(tt)$ pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or $F_1$ generation. All the $F_1$ plants obtained were tall.

Then, Mendel self-pollinated the $F_1$ plants and observed that all plants obtained in the $F_2$ generation were not tall. Instead, one-fourth of the $F_2$ plants were short.

Self-pollination of $F_1$ plants

From this experiment, Mendel concluded that the $F_1$ tall plants were not true breeding.

They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait.

Science

If a trait $A$ exists in $10\%$ of a population of an asexually reproducing species and a trait $B$ exists in $60\%$ of the same population, which trait is likely to have arisen earlier ?

A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as

A study found that children with light-coloured eyes are likely to have parents with light-coloured eyes. On this basis, can we say anything about whether the light eye colour trait is dominant or recessive ? Why or why not ?
