TT or tt
The correct option that shows all allele combinations that can be used to represent a purebred animal is:
TT or tt
To understand why TT or tt represents a purebred animal, we need to have some background knowledge about alleles and purebred animals.
Alleles are different forms of a gene that can occupy the same locus, or position, on a chromosome. In this case, we are considering a gene with two possible alleles: T and t.
Purebred animals are organisms that have the same alleles for a particular gene. They are homozygous for that gene, meaning they have two identical alleles at the corresponding locus.
In the case of the question, we are considering T and t as the two possible alleles. The combination TT represents a purebred animal because both alleles are the same, in this case, both alleles are T. Similarly, the combination tt also represents a purebred animal because both alleles are the same, in this case, both alleles are t.
Therefore, the option TT or tt shows all allele combinations that can be used to represent a purebred animal.
