11) purple flowers are dominant to white flowers in the jimsonweed plant. when a particular purple-flowered jimsonweed is self-pollinated, there are 28 purple-flowered and 10 white-flowered plants in the f1 generation. what are the genotypes of the parents? what is the phenotypic and genotypic ratio of the f1 generation

a) Genotypes of the parents - Pp

b) Phenotypic ratio -

c) genotypic ration -

Explanation:

It is given that 28 purple and 10 white flowered plants are produced in first generation.

Thus, genotype of the parents could be

Pp X Pp

As only then offspring with genotype PP, Pp, Pp, pp will be produced.

Thus, the phenotypic ratio would as PP, Pp Pp are purple flowered plant while pp is white flowered plant.

Genotypic ration would be PP:Pp:pp

a) Genotypes of the parents - Pp

b) Phenotypic ratio -

c) genotypic ration -

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity
