Answer: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
Explanation:
Mendel's monohybrid cross is definied as
Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)
Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)
[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]
The results in the F2 generation after a monohybrid cross: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
