A cross was carried out between a pure bred tall pea plant and a pure bred dwarf pea plant and $F_{1} $ progeny was obtained. Later, the $F_{1} $ progeny was selfed to obtain $F_{2} $ progeny. Answer the following questions:
(a) What is the phenotype of the $F_{2} $ progeny and why ?
(b) Give the phenotypic ratio of the $F_{2} $ progeny.
© Why is the $F_{2} $ progeny different from the $F_{2} $ progeny ?
(a) Tall, because genes responsible for tallness are dominant over dwarf trait.
(b) 
© Because in F_{2} generation, recessive genes got expressed in homozygous condition
