Q. 75.0( 1 Vote )

In peas, tallness is dominant over dwarfness, and red colour of flowers is dominant over the white colour. 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.

Answer :


GENOTYPE OF PARENTS: TTRR : ttrr that is 1:1


GENOTYPE OF OFFSPRINGS: TTRR : TTRr : TTrr : TtRR : TtRr : Ttrr : ttRR : ttRr : ttrr


1 : 2 : 1 : 2 : 4 : 2 : 1 : 2 : 1
