Character which falls to express itself in the first filial generation but emerges in the second is

The character which falls to express itself in the first filial generation but emerges in the second is a recessive trait. This means that the allele for the trait is present in the first generation but is masked by the dominant allele. However, in the second generation, the recessive allele can be expressed if both parents carry the recessive allele and pass it on to their offspring. The classic example of this is seen in Mendelian genetics with the inheritance of pea plant traits, where the wrinkled seed shape is a recessive trait.
