In daffodil plants, yellow flowers are dominant over white flowers. You discover a yellow plant and want to know whether it is homozygous for the yellow allele or heterozygous. You perform a test cross with a white-flowered plant.
a. Draw two Punnett squares for this test cross, one assuming a homozygous dominant yellow plant and one assuming a heterozygous plant.
b. If the offspring of your test cross all have yellow flowers, what does this tell you about the genotype of the yellow-flowered plant you started with?
