Solution:Gregor Mendel, the father of genetics, carried out his genetic experiments using pea plants (Pisum sativum). For this experiment, tall (TT) homozygous pea plants and dwarf (TT) homozygous pea plants were selected.
In the first filial generation (F1), only tall plants are formed.
-This shows that the gene for tallness in pea plants is dominant and dwarfness is recessive.
In the second filial generation (F2), tallness and dwarfness appear in plants in the ratio of 3:1 (3 tall and 1 dwarf).
Gregor Mendel
Gregor Mendel,The father of genetics by carrying out experiments on pea plants proposed laws of inheritance.
-Laws proposed by Mendel include Law of dominance(First law of inheritance),Law of segregation(Second law of inheritance)
and Law of independent assortment(Third law of inheritance)
Advantages of using pea plants in genetic experiments
