1.	What should be the genotype of a round seeded tall plant which when crossed with a plant of similar genotype produces the following percentage of phenotypes?(tall round = 56.25 %, tall wrinkled = 18.75 %, dwarf round=18.75 %, dwarf wrinkled = 6.25 %.)(A) Tt RR(B) TT Rr(C) Tt Rr(D) TTrr
Answer» (C) Tt Rr The ratio given is \(\rightarrow\) 9: 3: 3: 1 (56.25 : 18.75 : 18.75 : 6.25) This ratio occurs due to the F1 hybrid which is heterozygous for both the genes, i.e. TtRr.

Answer»

(C) Tt Rr

The ratio given is \(\rightarrow\) 9: 3: 3: 1 (56.25 : 18.75 : 18.75 : 6.25)

This ratio occurs due to the F1 hybrid which is heterozygous for both the genes, i.e. TtRr.
