Question

When the f1-generation plants were self-fertilised, he observed that in the plants of the second generation f2 both tall plants and dwarf plants were present. why it happened explain briefly

Answer 1

$\huge\mathfrak{Answer:-}$

⭕ Monohybrid Cross By Mendel :

⭕ At first Mendel crossed pure bred tall pea plant with pure bred dwarf pea plant.And He observed that only tall plants were produced in the first filial generation.✔️

⭕ When he produced the second generation by self pollinating the plants of first generation , he observed that 75 percent of the plants were tall and 25 percent of plants were dwarf.✔️

⭕ In other words we can say that the plants were in ratio of 3 :1.

$\huge\mathfrak{Conclusion:-}$

⭕ From this he concluded that traits are inherited independently.

⭕ Both dwarfness and tallness were inherited in the first generation but dwarfness was suppressed under the dominance of other.

⭕ Traits had not mixed up.If this would happen then plants with intermediate height would have been produced.This was not observed.❤️
