Instructions:
In a single-allele and complete dominance system, consider T = tall and t = short.
Using a Punnett Square, complete a cross between 2 heterozygous tall plants.
1) What is the genotype for heterozygous tall plants? (1 pt.)
2) Complete a Punnett Square using the above instructions. (5 pts.)
_____ _____
____
____
3) What is the phenotypic ratio?
(Your answer should include # phenotype : # phenotype.) (2 pts.)
4) What is the genotypic ratio?
(Your answer should include # genotype : # genotype.) (2 pts.)
5) If they do not have a homozygous genotype, explain why the heterozygous tall plants are still tall. (5 pts.)
6) In this example, for which kind of plant (tall or short) do you know its genotype just by looking at the plant? and why? (5 pts.)
