3. C. coccus (circular shape)
Explanation:
In self-pollinating plants, there is less dependence on the external factors to cause pollination. These plants depend on wind or other smaller insects that visit the flower regularly. In self- pollinating flowers, the anthers, and stigma are of similar lengths to facilitate the transfer of pollen.
First, we consider the parents:
Phenotypes: Polka dots
Genotypes: Pp
Using a punnet square,
P p
P PP Pp
p Pp pp
Therefore, out of four, the phenotypes and genotypes of the offspring will be as follows:
Phenotypes: 3 with polka dots (75%) and 1 with solid (25%)
Genotypes: 1 dominant homozygous (25%), 1 recessive homozygous (25%) and two dominant heterozygous (50%)
The answer is option D.
