A homozygous white-flowered plant is crossed with a homozygous dark purple-flowered plant. All of the seeds grow into pale purple-flowered plants. A) If there is no dosage effect, is it more appropriate to write the genotype for the white-flowered plant âWWâ or âppâ? B) What is your reasoning? (3 pts)
Uppercase letters are used to represent dominant genes and lowercase letters are used to represent recessive genes. All of the seeds grew into pale purple-flowered plants, the dominant gene would be purple and the recessive gene would be white. You would write the genotype for the white-flowered plant as âppâ instead of âWWâ because the white would be the recessive gene. How would I explain that they are both homozygous? Is this explanation correct?
Purple flower = PP
White flower = pp
