If purple flower color is dominant in pea plants, a cross between p generation purple and white plants will result ina. all purple flowers in the f1 generation. b. all white flowers in the f1 generation. c. all purple flowers in the f1 generation but a lighter purple than in the parents. d. mostly purple flowers in the p1 generation, with an occasional white flower. e. half of the plants having purple flowers, the other half having white flowers.

a. all purple flowers in the F1 generation.

Explanation:

According to the given information, the allele for purple flower color (lets assume P) is dominant over while the allele of flower color (p). When two pure breeding purple (PP) and white flowered (pp) plants are crossed, the F1 would have all "purple flowered progeny with genotype Pp".

According to the Mendel's law of dominance, the hybrid genotype exhibits the dominant phenotype. Here, the allele "P" is dominant over allele "p". Hence, the genotype "Pp" would exhibit purple flower color and all the F1 progeny would have purple flowers.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck
