Answer:

C) 75% blue-flowered and 25% white-flowered Eliminate

Explanation:

A square representation of a cross between the gametes of the parent allele for a specific trait is called a Punnett square. A cross between a single trait among the parental generation is called a monohybrid cross.

75% blue-flowered and 25% white-flowered is expected from this cross.

The Punnett cross between the flowers can be explained as:

Given,

The allele for the blue parent plant = Bb

See the attached image below for the cross.

  • Phenotypic ratio = 2:1
  • Genotypic ratio = 1:2:1

The physical attribute of flower colour will be seen as 75 % blue coloured and 25% white coloured flower as the cross was between two heterozygous species.

Thus, option C. 75% blue-flowered and 25% white-flowered will be observed.
