For the following problem give me a key for allele symbols, the genotype for each parent, a punnets square with the male and female symbols, and answers to the questions
In garden presses, tall vine is dominant and short vine is recessive. I’d a homozygous tall plant is crossed with a short plant, what genotypes are possible in the F, generation?

Allele key
- T = tall (dominant)
- t = short (recessive)

Parent genotypes
- Homozygous tall parent: TT (choose ♀ or ♂)
- Short parent: tt

Gametes
- TT parent → T, T
- tt parent → t, t

Punnett square (female on left, male on top)
♂ t ♂ t
♀ T | Tt | Tt
♀ T | Tt | Tt

Answers
- F1 genotypes possible: all offspring are Tt (100% heterozygous).
- F1 phenotypes: all tall (100% tall, 0% short).
