Answer #1

Monohybrid cross :

Parent gametes : P1P1 (pink) x P2P2 (Blue)

Gametes Blue : P2    P2
Pink : P1    P1P2 P1P2
   P1    P1P2 P1P2

As mentioned in the question that neither P1 nor P2 are dominant. Hence different phenotype is observed for the heterozygous alleles (P1P2) i.e. purple flowers.

So, all the possible phenotypes of the offspring are purple.

    II. MONOHYBRID PROBLEMS WITH INCOMPLETE DOMINANCE 8. Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R R are red-flowered, those that are heterozygous (R W ) are pink, while those with the (WW ) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1? __________________________________________________________ b. What...

    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...

    0. In snapdragons, the alleles for flower color show incomplete dominance. CRCR produces red flowers; CWCW produces white flowers and CRCW produces pink flowers. The height of the plant is determined by a separate gene with regular dominant and recessive alleles. Normal height (D) is dominant over dwarf height (d). a. A snapdragon that is heterozygous normal in height and has white flowers is crossed with a plant that is dwarf in height and has red flowers. What is the...

    In sweet peas, two genes (genes A and B) control flower color. The dominant alleles of both genes produce enzymes that function in the biochemical pathway shown to convert colorless precursors to a purple pigment. The recessive alleles do not produce enzyme. Therefore, at least one dominant allele of both gene A and gene B are required for purple flowers. Answer the questions about this biochemical pathway. ΑΑ, Αα BB, Bb Enzyme A Enzyme B Colorless precursor 1 Colorless precursor...
