Question

When a tall and red flowered individual is crossed with a dwarf and white flowered individual, phenotype in the progeny is dwarf and white. What will be the genotype of tall and red flowered individual?

Answer 1

Answer:

The genotype of tall and red flowered individual would be TtRr.

Explanation:

Let the allele for tall and dwarf plant be T , t

Let the allele for red and white flowered plant be R and r.

Given is genotype of recessive individual which is ttrr.

POSSIBLE GENOTYPES FOR TALL AND RED:

1) TTRR

2) TtRr

So we shall try for first case.

CASE 1 :

TTRR × ttrr

( look at the attachment)

In this cross we did not get any phenotype as dwarf and white .

So we will move to second case.

CASE 2:

TtRr × ttrr

( look at the attachment)

And here we obtain the phenotype as dwarf and white .

And so the genotype will be TtRr.
