Question

genes, which are portions of your dna, code for your traits. the ability to taste the chemical ptc is determined by your genes. if youve ever done this test, i am sure you will remember if you have the trait of being able to taste ptc - rumor has it that its super bitter! what type of trait is the ability to taste ptc? its so gross! hehehe! haha, ewww! yuck! co-dominant dominant recessive

Explanation:

The ability to taste PTC is a dominant trait. In genetics, a dominant trait is one that is expressed when at least one dominant allele is present. The PTC tasting trait is determined by a dominant allele (T), so if an individual has at least one T allele (TT or Tt), they can taste PTC. Recessive traits require two recessive alleles to be expressed, and co - dominant traits involve both alleles being fully expressed in a heterozygote, which is not the case for PTC tasting.

Answer:

B. dominant (assuming the options are labeled as A. co - dominant, B. dominant, C. recessive)
