Answer:
It forms from the surface downward toward the parent rock.
Explanation:
A typical soil does not form from the surface downward toward the parent rock.
Soil is formed by the weathering of the parent rock. During weathering, a rock is broken down into smaller fragments by chemical and physical means.
- From the bedrock, as the disintegration proceeds, fine particles of earth are formed.
- This in turn gets mixed with organic matter, water and air to form a full soil profile.
- Soil takes a very long time to form.

Homozygous recessive: tt
Heterozygous: Tt
Cross:
t t
T Tt Tt
t tt tt
Thus, the expected outcome genotypic ratio is:
1 Tt : 1 tt
