Most of the individuals of a certain wildflower population have white flowers, although a few are purple-flowered. Crosses have demonstrated that allele for white color flower (W) is dominant over the allele for purple (w). Give the genotype of a purple-flowered plant, and show the gametes that it would produce as a result of meiosis. If two heterozygous whoite-flowered plants are crossed. What fraction of the offspring do you expect to be purple? If two purple-flowered plants are crossed, what fraction of their offspring do you expect to be white?

Question

 Most of the individuals of a certain wildflower population have white flowers, although a few are purple-flowered. Crosses have demonstrated that allele for white color flower (W) is dominant over the allele for purple (w).

    1. Give the genotype of a purple-flowered plant, and show the gametes that it would produce as a result of meiosis.
    2. If two heterozygous whoite-flowered plants are crossed. What fraction of the offspring do you expect to be purple?
    3. If two purple-flowered plants are crossed, what fraction of their offspring do you expect to be white?
