Q. 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 by a dwarf plant bearing White flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them.
Mention the genotypes of the two parents and of the types of four offspring.
Dear student,
Please find below the solution to the asked query
Parents: TTRR (tall and red) x ttrr (dwarf and white)
Gametes: TR, tr
F1 progeny: TtRr
Four gametes formed will be TR, tR, Tr and tr.
F2 generation:
Four offsprings formed are- tall and red (TTRR, TtRR, TTRr, TtRr), tall and white (TTrr, Ttrr), dwarf and red (ttRr, ttRR), and dwarf and white (ttrr).
Please find below the solution to the asked query
Parents: TTRR (tall and red) x ttrr (dwarf and white)
Gametes: TR, tr
F1 progeny: TtRr
Four gametes formed will be TR, tR, Tr and tr.
F2 generation:
| TR | tR | Tr | tr | |
| TR | TTRR | TtRR | TTRr | TtRr |
| tR | TtRR | ttRR | TtRr | ttRr |
| Tr | TTRr | TtRr | TTrr | Ttrr |
| tr | TtRr | ttRr | Ttrr | ttrr |
Four offsprings formed are- tall and red (TTRR, TtRR, TTRr, TtRr), tall and white (TTrr, Ttrr), dwarf and red (ttRr, ttRR), and dwarf and white (ttrr).
