How do Mendel’s experiments show that traits may be dominant or recessive?
Mendel crossed a tall plant with a short plant. All the plants in the first generation were tall. This means the tall trait hides the short trait.
When these tall plants were crossed again, the short plants came back in the next generation.
This showed that:
Tall trait = dominant (shows itself)
Short trait = recessive (gets hidden but is not lost)
So Mendel proved that some traits hide others, which is why they are called dominant and recessive.

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?

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) TTWW (b) TTww (c) TtWW (d) TtWw
