The genotype for the height of an organism is written as Tt. What conclusion may be drawn?
Answer: There are at least two different alleles of the gene for height
Explanation
The genotype Tt represents two different alleles of the same gene:
- T = dominant allele (e.g., tall)
- t = recessive allele (e.g., short)
This means the organism is heterozygous for the height gene — it has two different alleles (T and t) of one gene.
