Answer:
The continuation of the question is
Which explains why this is the case?
Their DNA is made of different codon sequences.
Their DNA is made of four different bases.
Kai inherited more proteins from one parent than the other.
Kai inherited different amino acids from either of her parents.
The answer is Their DNA is made of different codon sequences.
DNA which is also called Deoxyribonucleic acid contains nitrogenous base pairs, deoxyribose sugar and a phosphate group. The amino acids which are found in the base pairs are responsible for the different traits expression. This is possible as a result of the different coding sequences as there are more than 60 codon sequences. This is why there is a slight variation between Kai and her parents.
