Mendel worked out the rules of heredity by working on garden pea using a number of visible contrasting characters. He conducted several experiments by making a cross with one or two pairs of contrasting characters of pea plant. On the basis of his observations he gave some interpretations which helped to study the mechanism of inheritance.
Mendel crossed pure tall pea plants (TT) with pure short pea plants (tt) and obtained F₁ progeny. When the plants of F₁ progeny were self-pollinated, plants of F₂ progeny were obtained.
On crossing a tall and a short pea plant, Mendel obtained F₁ generation in which all pea plants were tall.
In an experiment to study independent inheritance of two separate traits : shape and colour of seeds, the ratio of the different combinations in F₂ progeny would be
List any two pairs of visible contrasting characters of garden pea plants used by Mendel for his experiments stating the dominant and recessive characters in each pair.
In human beings, the probability of getting a male or a female child is 50%. Explain with the help of a flow diagram only.
