All three scientists would most effectively demonstrate their concepts by using models.
Models are often used in science to provide a simplified visual representation of a certain phenomenon, making it easier to observe, understand and predict the possible future outcomes or effects of the demonstrated phenomena.
Answer:
Correct answer is A and B.
Explanation:
Because the Tonkinese breed has a coat that is intermediate to the coat color of the Siamese and Burmese, we can say that this demonstrates incomplete dominance which means that the dominant allele does not have the ability to completely mute the recessive allele in the phenotype.
This is also true because of the development points on the coat of the Tonkinese breed.
So the correct answer is A and B.
I hope this answer helps.
