Homework Answers
Ans:
a)
| Color | fo | pi | fe | (fo-fe)^2/fe |
| black | 306 | 12/16 | 299.25 | 0.1523 |
| brown | 66 | 3/16 | 74.81 | 1.0381 |
| pale | 27 | 1/16 | 24.94 | 0.1706 |
| Total | 399 | 399 | 1.3609 |
Test statistic:
chi square=1.3609
b)df=3-1=2
critical value=CHIINV(0.05,2)=5.991
c)Option B is correct.
We conclude that theory is true since the answer in (a) is less tha n or equal to the answer in (b)

Problem #1: (a) Suppose that we identify 169 women 50 to 54 years of age who have both a mother and a sister with a history of breast cancer. 17 of these women themselves have developed breast cancer at some time in their lives. If we assume that the proportion of breast cancer cases in women whose mothers have had breast cancer is 8%, does having a sister with the disease increase the risk? Find the p-value. (b) At the...

1. At least 3 independently assorting loci are known to govern coat color in mice. The genotype C- will allow pigment to be produced by 2 other genes. The cc genotype does not allow pigment production resulting in albino mice. The striped “agouti” hair pattern depends on the genotype A- and the aa genotype is nonagouti. Finally, the color of the pigment may be black (B-) or brown (bb). Five different coat colors may be produced by the action of...

Data from adoption studies on handedness indicate that the
effects of shared biological heritage are more powerful
determinants of hand preference than sociocultural factors.
Biological offspring were found to show nonrandom distributions of
right and non-right handedness as a function of parental
handedness. In contrast, the handedness distribution of adopted
children as a function of parental handedness was essentially
random. The following table gives the handedness of biological
offspring as a function of parental handedness.

1. In Eastern Gray Squirrels, the allele for Greay coat color (G) is dominant to the allele for black coat color (g). In a population of 200 squirrels, there are 18 black squirrels. The population is in Hardy-Weinberg equilibrium. a. What is the genotype of the 18 black squirrels? b. What is the frequency of the bb genotype in this population? c. What is the frequency of the b allele? d. What is the frequency of the B allele? e....
