Question

in a field when the cross was performed between tall and
dwarf plants, 270 tall and 90 dwarf plants were obtained in F2
generation. Explain these observations with the help of a
cross and relevant principles of inheritance?​

Answer 1

Answer:

let tall be TT and short be tt.

then upon crossing,

TTxtt = Tt ----> F1 generation.

then F2 generation = self pollination of F1

= TtxTt = TT, Tt, Tt, and tt.

this ratio of tall to short is 3:1 in the F2 generation, yes?

so, from the question, when we see the ratio of tall to short, we get

270:90.

= 3:1.

Show this, and then state the Law of Segregation/Inheritance.
