Answer:
b) More than two alleles exist
Explanation:
There are cases where more than two alleles determine a character in the population. This type of inheritance is called multiple alleles (or polyalelia). Classical examples of polyalelia are hair color determination in rabbits and blood groups of the ABO system in humans.
In the attached figure we can see another example of polyalelia where a flower is self-fertilized generating different phenotypes in its offspring.
The correct answer is "<span>result in a shortened polypeptide chain".
This is a defect in the genetic code wherein the mRNA transcribed from the DNA has a premature stop codon. A stop codon is a codon (three nucleotides) which will signal the translation process to stop by a release factor. The stop codons for humans are UAA, UAG, and UGA. In the event where there is a mutation involving a premature stop codon in the mRNA, then the translation process will end prematurely making the elongating polypeptide chain to also release prematurely. This polypeptide chain is shortened as the elongation process is interrupted.</span>
