184395 A true breeding plant producing red flowers is crossed with a pure plant producing white flowers. Allele for red colour of flower is dominant. After selfing the plants of first filial generation, the proportion of plants producing white flowers in the progeny would be

1 \(\frac{3}{4}\)
2 \(\frac{1}{4}\)
3 \(\frac{1}{3}\)
4 \(\frac{1}{2}\)

184396 A pure tall pea plant was reared in soil poor in nutrition and reached the size of pure dwarf pea plant, if this plant is selfed, then the genotype in the \(F_{1}\) - generation is most likely to be

1 all tall
2 \(50 \%\) tall: \(50 \%\) dwarf
3 all dwarf
4 Not possible: to predict

1 \(3: 1\)
2 \(1: 1\)
3 \(9: 3: 3: 1\)
