LONG ANSWER QUESTION #2   Assume the following population with two alleles of a given gene, A1 and A2.    GENOTYPE    NUMBER OBSERVED A1/A1                  46 A1/A2                  11 A2/A2                  23   Calculate the genotypic frequency and allelic frequency using the information provided above, then using that information, calculate the expected genotypic frequency of each genotype assuming the population is at Hardy-Weinberg equilibrium for the gene in question. To answer this question fully, you should have eight values (or answers) to present for your answer. For credit, show your work and ensure your answers are clearly noted/identified. (8pts)

A Mendelian trait ____.  

For which two codons below could a single base change account for this amino acid change?    Serine –> Cysteine  

Hershey and Chase chose 35P and 32S in their experiment because nucleic acids contain large amounts of phosphorus and no sulfur.   

You are studying a species of rabbits and are analyzing eight genes, each having two alleles that demonstrate a simple pattern of Mendelian inheritance. Alleles indicated by capital letters are dominant to alleles indicated by lowercase letters. You set up the following cross:   AA BB cc DD EE Ff Gg hh    x   AA bb CC Dd EE ff gg HH    How many of the eight phenotypes are shared by the two rabbits in the cross indicated above?   

SHORT ANSWER QUESTION #9   According to what was discussed in class, only, please the following terms in order of increasingly condensed: nucleosome, naked DNA, histones, chromatin. (1pt)   NOTE: When writing your response, note I am not looking for what Google or Chat GPT provides you as an answer to this ordering question. Only responses derived from material from the course textbook, course lecture videos, or course powerpoint will be accepted. 

Epigenetic changes are changes that alter the base sequence of DNA, thus modifying gene expression.
