which describes the notation tt for the trait of plant height?○ homozygous genotype○ heterozygous genotype○ homozygous phenotype○ heterozygous phenotype

Answer

Answer:

B. heterozygous genotype

Brief Explanations:

  • Genotype refers to the genetic makeup (the pair of alleles) for a trait, while phenotype is the observable physical expression of the trait, so the options referencing phenotype are incorrect.
  • A heterozygous genotype has two different alleles (one dominant, one recessive, represented here as T and t), whereas a homozygous genotype has two identical alleles (TT or tt). The notation Tt matches the definition of a heterozygous genotype.
