Explanation:
it is a monohybrid cross. Let A be the dominant allele and 'a' be the recessive allele. When Aa ( tall plant ) is crossed with Aa ( dwarf plant), the the F2 generation will produce offsprings which will be 3 Tall and 1 dwarf. parents AA (tall) X aa(dwarf) F1- Aa(tall) F1 X F1 Aa X Aa F2 generation 1 AA (tall): 2 Aa (tall ): 1 aa (dwarf) Phenotypic ration 3 tall: 1 dwarf
