When crossing a plant that is homozygous dominant for flower color (purple) with a plant that is homozygous recessive for flower color (white), the F1 generation is: Select one of stion O a homozygous and white b. homozygous and purple c. heterozygous and white d heterozygous and purple
Answers
The correct answer is
D) heterozygous and purple.
The two flowers that were crossed in the above experiment were a homozygous dominant purple and a homozygous recessive white. Because of this each of the offspring in the F1 generation were all heterozygous making them purple which is 100% (Pp) according to Mendel's laws of inheritance.
