In some situations, when two purple-flowered pea plants reproduce, the offspring can have purple or white flowers. When this experiment is run repeatedly, it is discovered that three-fourths of the offspring have purple flowers and one-fourth of the offspring have white flowers.

What would happen if this experiment were run only once?

The experiment would give the same results. The conclusion would not be changed from the original experiment.

The experiment would give a single white-flowered plant. The conclusion would be that tall plants always produce white-flowered plants.

The experiment would give a single purple-flowered plant. The conclusion would be that tall plants always produce purple-flowered plants.

The experiment would result in a plant with either purple or white flowers. The conclusion would depend on this single result and would not be accurate.

Answer :

The experiment would give the same results. The conclusion would not be changed from the original experiment.

Explanation:

The alleles for the purple colour flower in Mendelian pea plant is Pp

This means this is a heterozygous dominant in nature.

Pp and Pp are the heterozygous plants with purple colour to be crossed.

  Punnett square, F1 generation

     P     p

P   PP  Pp

p    Pp   pp

3 purple one white

ie 3/4 th purple and 1/4 white flower

Phenotypic ratio 3:1

genotype ratio  1:2:1

The phenotype ratio shows only one white flower in the first generation.

Answer:

The experiment would result in a plant with either purple or white flowers. The conclusion would depend on this single result and would not be accurate.
