An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.

Answer:

Codominance

Explanation:

That would be Codominance.  Codominance means that neither allele can mask the expression of the other allele (Both are dominant alleles, no recessive alleles). This is because the flower isn't only red or only pink. It has both alleles (which causes the red and pink stripes).
