Problem:

A new variety of campion has been discovered that has either red or white flowers. Campions are dioecious plants that have male and female forms. As well as autosomal chromosomes, campion has a pair of sex chromosomes. Female forms have two X chromosomes and male forms have an X and Y chromosome. Red flowered male plants were crossed to white flowered female plants. The progeny from this cross were examined and it was found that there were only white-flowered male plants and red-flowered female plants.

Required:

Question 1: What can you deduce from these results?

Question 2: Using the progeny from the cross described above, suggest an experiment to test whether all possible combinations of gender and color can occur. Show your work.
