If a tan mouse lives in a hayfield, will it have the best chance of living and passing on its genes based on our experiment today?
Field mice have either tan, black or white backs and are prey to hawks. We are learning about 'CRISPR' and genes

Consider island C in 1980 with the following phenotypic frequencies....conduct chi-square analysis
Consider island C in 1980 with the following phenotypic frequencies for (long)= 315 (medium) = 200 (short) = 36.Conduct chi-square analysis. I'm not sure how to calculate the Chi-square value. How... more
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 migration rates are high, then ____________________________________.
I think the answer is C, but I am not sure. I think dependent because migration and mutations allele frequency will be affected in multiple populations. A) different alleles will become fixed in... more
What does it mean if something is stochastic?
I think the answer is C because if you have a bunch of data you can find the avg. and potentially predict what may happen next. So maybe you can predict the probability of a mutation in a... more
Which of the following statements is true about the equilibrium frequency?
Hi, I think the answer is C because when the mutations even out, they ,maybe will become fixed. I'm not sure though because I know hardy Weinberg equilibrium occurs when there are no mutations.... more
