Please be kind and help me ​

Answer 1

Let us take the following example to justify the above statement.

Mendel crossed tall pea plants with dwarf pea plants.

Mendel's Observation  F1 generation contained all tall plants. When F1 generation underwent selfing, the trait that was unexpressed in F1 (dwarf) was observed in some F2 progeny. Thus, both traits, tall and dwarf, were expressed in F2 generation in the ratio 3 : 1. 

The above experiment indicates that although both the traits of tallness and shortness were inherited in F1 plants, only the tallness trait was expressed. This shows that traits may not show up in an individual but are passed on to the next generation.

Answer 2

The example is recessive trait. I { Atul} stated that tallness in pea plant is dominant over dwarfness. When tall and dwarf pea plants are crossed. Then in X1 all plant born are tall (dwarf does not express) itself, it remains hidden). But when F1 plants are selfed, the recessive trait dwarfness reappears in X2 generation in ratio of 3 tall : 1 dwarf.

We can say any other plant also..or example of a person who has been inherited but not revealed socially in public

Here dwarfness is whose height is short
