Final answer:
A) Purebred. A trait which results from two dominant genes is called purebred or hyper dominant.
Step-by-step explanation:
A trait which results from two dominant genes is called purebred or hyper dominant.
To understand this concept, let's consider an example of flower color in pea plants. Let's say the dominant allele (trait) for flower color is represented by 'A', and the recessive allele (trait) is represented by 'a'.
If an individual has two dominant alleles for flower color (AA), it will be purebred or hyper dominant for that trait. This means that the individual will always display the dominant phenotype of the trait, in this case, the dominant flower color.
So, the correct answer is A) Purebred.
