Question 1

A plant with the genotype Tt is crossed with a plant of unknown genotype that produces dwarf offspring. Determine the genotype of the unknown parent and explain your reasoning.

💡 Hint: Pay attention to the offspring's trait produced.

Question 2

If TT and tt plants are crossed, what will be the genotypic and phenotypic ratios in the offspring? Discuss the implications for future generations if two Tt offspring are bred.
