Question

2.When a pure bred tall pea plant with violet flowers were crossed with a pure dwarf pea plant with white flowers, all the plants in F1 generation were found to be tall plants with violet flowers. If these plants were self pollinated,what will be the outcome of the second generation. Find the phenotype and the genotype of F2.Draw Punnett square for F2.if u are spamming i know a moderater i will tell him to block u from brainly

Answer 1

Answer:

In first cross TTVV x TTVV =all TtVv

here TtVv are F1 generation

(all tall and violet hybrids).

when F1 progeny are selfed

TtVv x TtVv

then the process and result will be same as the dihybrid cross given in ncert ,just replace RrYy to TtVv.

therefore the phenotypic ratio will be 9:3:3:1.

and genotypic ratio will begin 1:2:1:2:4:2:1:2:1
