Explanation:

Question 1

TT or Tt with capital letters represent dominant genes. From the word bank, "Dominant" fits as these genotypes show dominant traits.

A true - bred organism has the same alleles for a trait, so it is homozygous. The hint "same alleles" and the word bank term "Homozygous" match.

TT is a homozygous dominant genotype (both alleles dominant). So it represents a "Homozygous Dominant" trait.

Answer:

Dominant
