Open in App
Solution
The correct option is D pea plant bearing violet flowers or a pea plant bearing white flowers
Violet colour of flowers is dominant over white colour of flowers in pea plants.
Allele for violet flowers is P and for white flowers is p. Hence the genotype of plants bearing violet flowers is PP or Pp.
When a pea plant heterozygous for violet flowers (Pp) is crossed with another pea plant heterozygous for violet flowers (Pp), then the progeny will have plants producing violet and white flowers in the ratio of 3 : 1. Hence this cross has the possibility of offspring bearing white flowers.
Another possibility of offspring with white flowers is by crossing the plant heterozygous for violet flowers ( Pp) with a plant bearing white flowers (pp). The ratio of violet : white will be 1: 1.
