Answer:
The offspring plant must have genotype Rr for flower color (pink flowers) and Ww for seed shape (wrinkled). In fact we know more: we know the R and W came from one parent, so are on the same chromosome, and also the r and w on the other chromosome, from the other parent. We write this RW/rw.
Explanation:
When the genotype of a carnation is heterozygous for the trait (Rr), the result is a pink color that comes from the incomplete dominance of the alleles. In codominance there are two or more dominant alleles.
Answer:
Mutualism
Explanation:
This type of relationship is where all organisms involved benefit from the interaction. The relationship can be obligatory (where the organisms cannot live independent of each other) or can be facultative (where they can also live independent of each other). In lichen, this relationship is facultative.
