Homework 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.

Following the genetics of Mendel, where purple is dominant and white is recessive for flower color, which of the following would allow one to determine the genotype of a purple flowered pea plant?

In the Japanese morning glory, purple flower color may be caused by dominant alleles at either...
In the Japanese morning glory, purple flower color may be caused by dominant alleles at either one of two separate gene pairs, A_bb or aaB_. When dominant alleles are present at both gene pairs (A_B_), the flower color is blue, and when both are homozygous recessive (aabb), the color is scarlet. A blue F1 was therefore produced by crossing two different purple types AAbb x aaBB. A. What phenotypes in what proportion would you expect from crossing this F1 to...

In an experiment, homozygous dominant plants with purple flowers were crossed with homozygous recessive plants with white flowers. Mendel collected the seeds from this cross, grew F1-generation plants, crossed them to form a second generation, and then analyzed the plants of the resulting F2 generation. What results did he probably get? 1/2 the F1 and 3/4 of the F2 generation flowers were white 1/2 the F1 and 1/4 of the F2 generation flowers were purple 3/4 of the F1 and...
