Explanation:

Lycopodium is known as as ground pine, and is a genus of clubmosses. They are homosporus, because they produce only one type of sporangia, while Selaginella are heterosporus, because they produce microspores and megaspores, and they are known as spike moss. Both of them, lycopodium and selaginella can have strobili.

answer; i believe the correct answer is (anemia);

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
