Question

Tall (T) is completely dominant over dwarf (t). Red flower colour (R) is incompletely dominant over white (r), the heterozygous being pink. Plant having genotype of TtRr is self pollinated. What would be the proportion of plants with dwarf and pink characters in the progeny

• A. 2/16
• B. 1/16
• C. 9/16
• D. 3/16.

Answer 1

The correct option is A 2/16

A tall plant with red flowers(TTRR) is crossed to dwarf plant with white flowers(ttrr). In the F1 generation, tall plant with pink flowers are formed(TtRR). When F1 plant is self pollinated, in the F2 generation 3 Tall plants with red flowers, 6 tall plants with pink flowers, 3 tall plants with white flowers, 1 dwarf plant with red flowers, 2 dwarf plants with pink flowers, 1 dwarf plant with white flowers are formed.

So, the correct option is ‘2/16’.
