Animals that select mates that are phenotypically similar will have ________ when compared with Hardy-Weinberg predictions.

Production of the iron-storing protein ferritin is regulated by aconitase, which binds to a 30-nucleotide sequence at the beginning of the ferritin mRNA and interferes with ribosome binding. Aconitase must be a

You are walking around campus and you are in luck! A table has been set up to collect volunteers’ DNA samples for free complete genomic sequencing! You have heard about this in the news, and thanks to this course, you have some concerns. Which of the following statements regarding genomic sequencing is NOT true?

The phenotype for a mouse is either dominant, (brown BB), or recessive, (white bb). If 40% of the mouse population is white, what is the percentage of mice in the population that are heterozygous? What is the frequency of homozygous dominant individuals?
