Question

state the type of plants not found in F1 generation but appeared in F2 generation mentioning the reason for the same.

Answer 1

dont not appear the F1 generation are the dwarf plants. This is because the dwarf plants are homozygous recessive alleles. The recessive character does not appear in the presence of the dominant character . But when the F1 were cross fertilsed the recessive character expresses itself in the absence of the dominant trait.
I hope it's helps u alot plZ marks as brilliant answer.

Answer 2

characters of pea plant choose by Mendel were height of plant (tall and dwarf), postion of flower (axillary,terminal ),pod colour (green ,yellow) ,pod shape (inflated ,constricted ), flower colour (violet ,white), seed color (yellow ,green ) and seed shape (round wrinke).Type of plants not found in F1 generation were dwarf plant or
terminal plant or yellow pod color or constriced pod shape or white flower colour or green seed color or wrinKle seed shape . Later it was observed that the traits which were reccesive do not appeared in F1 generation where Dominant traits appeared in F1 generation. The reason was the Law of Dominance. Law of Dominance states that when alternate forms of characters came together then only one of them is able to express itself . that is called as dominant and this law is called as law of Dominance.
