Given three possible phenotypes for parents showing dominance (aa, aa, aa), which combination would produce a 1: 2: 1 ratio of genotypes and a 3: 1 ratio of phenotypes?
i. aa x aa
ii. aa x aa
iii. heterozygous x heterozygous
iv. aa x aa
v. homozygous dominant x heterozygous
a) i, ii, iii, iv, and v only
b) iii and iv only
c) i and v only
d) ii only

I’m guessing C because it’s mostly understandable to me message me of im incorrect

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
