A point mutation would be most likely to impact the protein because during point mutation one or some bases in a nucleotide sequence of the open reading frame of mRNA get mutated.
Explanation:
The mutation in one nucleotide of an open reading frame(containing specifically arranged codons)of mRNA is enough to change the normal open reading frame by changing only a single codon.
Changing a single codon will alter the amino acid specific for that codon but alteration of a single amino acid can form an abnormal or disease causing protein.
The chromosomes in the sex cells would be half the chromosomes in the body cells; so since each body cell has 40 <span>chromosomes and half of that is 20, there's your answer. It's B. 20</span>
