D Bc I just did it and got it right
Trophic Levels describe the transfer and different stages of the organisms transferring energy. I just called it Trophic level energy flow in school.
C! I just did cells and their organelles!
So Mendel got roughly 75% yellow and 25% green in f2. This means that f1 contains all heterozygous genes, as shown below
Y y
Y YY Yy
y Yy yy
Summary: 75% YY or Yy, 25% yy
Which means that green (y) is a recessive phenotype, while yellow (Y) is a dominant phenotype, since plants with heterozygous genotype Yy express the yellow trait.
