Question

In your garden, you are growing several plants of the species Florus imaginarium. You have observed that some of the individuals have leaves with rounded tips and others have leaves with pointed tips. One of these traits is dominant and the other is recessive. Assuming all the plants in your garden are true-breeding, how would you go about determining which trait is dominant and recessive?

Answer 1

you would begin to cross breed these plants, and examine the ratios which occurred afterwards.  If all of the F1 generation had pointed tips, that would be the dominant allele.
