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.
Cross: between two medium Gazorps
Parentals) Tt x Tt
Gametes) T t T t
Punnett square) T t
T TT Tt
t tT tt
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
