Consider island C in 1980 with 546 adults. If the frequency of the black allele (f(y)) is 0.12, assume Hardy-Weinberg conditions and estimate the frequency of heterozygotes in this island population?
Options(A) 0.0<f(Yy)<0.2(B) 0.2< f(Yy) <0.4(C) 0.4< f(Yy) <0.6(D) 0.6< f(Yy) <0.8(E) 0.8< f(Yy) <1.0I think the answer is B, but I'm not sure.

If an exercise asks for the number of informational rna nucleotides, does stop, nonsence codone (3 nucleotides) count?
For example, if we have 300 amino acid in protein, do we count nucleotides of rna like 300×3+3 or just 300×3 and why so?? I dont get it, cause nonsence triplet is also a part of rna right?

If a mutation is irreversible, then the original allele will eventually go extinct in the population. (True or False)
I said it was false because I think the original allele can be recessive and also I think it means that mutation will become fixed.
