Hey there! :D
When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".
I hope this helps!

Sycamore trees (Platanus occidentalis) make handsome shade trees for large landscapes.
Explore a wide variety of cells, from bacteria to human neurons, using a compound light microscope. Select a sample to study, then focus on the sample using the coarse and fine focus controls of the microscope. Compare the structures found in different cells, then perform tests to see if the sample is alive.
The primary consumers like rabbits or other small animals that are normally eaten by the secondary consumers (snakes) would over populate and eat all of the producers (plants) and the plants would die out. This would eventually lead to the decrease of the primary consumer (rabbit/small animals) population.
