Answer:
The correct answer would be C. Left untreated, it can cause intellectual disability.
Phenylketonuria (PKU) is a rare autosomal recessive disorder caused by a defect in a gene responsible for making phenylalanine digesting enzyme.
This defect leads to the lack or deficiency of this enzyme in the body. Consequently, phenylalanine builds up in the body.
People with this disorder are usually put on a restricted diet which restricts protein-rich food (such as milk, meat, cheese etc as they contain amino acid phenylalanine) from their meals.
Untreated PKU can cause various complications such as brain damage (intellectual disability), neurological problems, major health and development problems etc.
They both have similar environments, which show they have evolved similar behaviors and appearances. hope this helps <3
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.
