If a point mutation occurs in a body cell so that the original sequence of mRNA of CGA changes to AGA, what will be the likely consequence?
A. The mutation will cause a translocation to occur.
B. The mutation will cause a change in the individual but it will not be inherited.
C. The mutation will be inherited by the offspring.
D. The mutation will not cause any change in the individual and it will not be inherited.

So would it be B? Because I know that point mutation can cause a change but I just don't know if it is inherited or not.

@Haileys0211 Basically, nothing. CGA is arginine AGA is also arginine. So it is C, the mutation will be inherited because it will have zero effect on the functioning of whatever it is coding for and therefore will have a zero effect on the fitness.

You always need to check what the codon (three nucleotide sequence) will code for and what the mutation will code for. Just google or bing or whatever, codon table or codon chart.
