Question

In a pea plant the trait of flowers bearing purple colour (PP) is dominant over white colour (PP) . Explain the inheritance of traits. State the visible characters of F1 and F2 progenies​

Answer 1

Purple Flowers {PP}

White Flowers  {pp}

                 On Cross-Pollination of [PP] and [pp]

  All plants obtained in the F1 Progeny will be having Purple flowers but, with heterozygous traits (means both traits will not be same i.e. one will be dominant while other will be recessive). (Pp) will be found.

            On Self-Pollination of F1 Progeny F2 Progeny will be produced

In this, 4 PLants will be produced.Among them 1 will have pure traits i.e. [PP] so,will bear purple flowers and 2 will have impure traits i.e. [Pp] but will bear purple flowers due to dominance of Purple colour trait .The remaining 1 plant will have both recessive traits i.e [pp] so,it will bear white flowers.
