Suppose you have a pea plant with purple flowers, and you are asked what is its genotype. You do not know what its parents looked like and cannot find this information anywhere. You have no other plants to mate it with. How can you find out what its genotype is? explain fully.

You look it up from people who did know what the parents looked like and did do the mating experiments.

Pea plants are monoecious, possessing male and female parts on the same flower. Self-fertilize it. If it's homozygous, all the offspring will be like the parent. If it's heterozygous, you'll get the usual 3:1 mix of phenotypes.
