Sedimentary rocks are formedwhen sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rockinto loose material in a source area.
Answer:
- 25 tall individuals, TT
- 50 medium individuals, Tt
- 25 short individuals, tt
Explanation:
<u>Available data</u>:
- The size of this species was determined by a single gene
- TT- Tall
- Tt- Medium
- tt- Short
- Total number of individuals in the progeny, N = 100
There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.

Parentals) Tt x Tt

Punnett square) T t

F1) 1/4 = 25% TT, tall
2/4 = 1/2 = 50% Tt, medium
1/4 = 25% tt, short
100% of the progeny ------------ 100 individuals
25% Tall, TT ------------------------X = 25 individuals
50% Medium, Tt -------------------X = 50 individuals
25% Short, tt ------------------------X = 25 individuals
