In peas, tellenss is dominate over dqarfness, and red colour of flowers is dominant over the white coolour. When a tall plant bearing red flowers was pollinated with a dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them
Tall, Red = 138
Tall, White = 132
Dwarf, Red = 136
Dwarf, White = 128
Mention the genotypes of the two parents and of the four offspring types.

Text Solution

Verified by Experts

Four types of offspring are in a ratio of `1:1:1:1`
Such a result is obtained in a test-cross progeny of a dihyvrid cross.
The cross can be shown as:
Tall & Red (Tt Rr)`xx`Dwarf & white (ttrr)
Offsprings
Tt Rr-Tall,Red
Tt rr-Tall,White
Tt Rr-dwarf ,red
tt rr-dwarf,white
Ratio `1:1:1:1`
