When the phenotype ratio of the resulting offsrping is 9:3:3:1, the genotype of the plant will be ttpp. The genotype of the plant whose phenotype appeared once out of every 16 offspring the "1" in the 9:3:3:1 ratio is ttpp. So the answer in this question is ttpp.
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III
