Answer:
See the answer below
Explanation:
Let the tallness be represented by T and the shortness by t.
True-breeding tall plant = TT
True-breeding short plant = tt
TT x tt
Tt Tt Tt TT
Genotypic ratio of offspring: 100% Tt
Phenotypic ratio of offspring: 100% tall (see the first attached image for the Punnet's square analysis)
(a) See the second attached image for the Punnet's square analysis.
Tt x Tt
TT Tt Tt tt
Expected genotypes
- 1/4 TT
- 1/2 Tt
- 1/4 tt
Expected phenotypes
- Tall - 75%
- Short - 25%
(b) Tt x tt
Tt Tt tt tt
Expected genotypes
- 1/2 Tt
- 1/2 tt
Expected phenotypes
- Tall - 50%
- Short - 50%
The kind of cross if referred to as test crossing.
(c) Tt x TT
TT TT Tt Tt
Expected genotypes
- 1/2 TT
- 1/2 Tt
Expected phenotypes
- Tall - 100%
