Question
Chapter 12.4, Problem 1TC
Summary Introduction
To determine: The outcome of natural selection on myostatin alleles.
Introduction: Myostatin, also known as growth differentiation factor 8 is a myokine protein that is released by myocytes. It has an autocrine function of inhibiting myogenesis, which is essential for muscle cell growth and differentiation. A mutation in the coding region of myostatin results in a double-muscle trait in cattle.

According to a recent study, 1 out of 50,000 people will be diagnosed with
cystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene
(dominant gene symbol is F and mutant is f).
A. Using the rate of incidence above, what is the frequency of carriers of the
cystic fibrosis allele for CFTR in the US? (3 pts)
B. In a clinical study, 400 people from the population mentioned in (A.) were
genotyped for BRCA1 Listed below are the results. Are these results in Hardy-
Weinberg equilibrium? Use Chi Square to show whether or not they are. (3 pts)

Case Study—Ella
Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
