A table represents the possibility of an association between eye
color and hair color.
| Hair Color | ||
| Eye Color | Brown | Black |
| Green | 22 | 15 |
| Blue | 18 | 19 |
In order to determine if there is a significant difference between
eye color and hair color, the chi-square test for association and
independence should be performed.
What is the expected frequency of Blue Eyes and Black
Hair?
- a.)
20
- b.)
17
- c.)
19
- d.)
18
Homework Answers
Solution :
The observed frequencies are
Hair color
| Eye color Brown Black Total |
| Green 22 15 37 |
| Blue 18 19 37 |
| Total 40 34 74 |
The expected frequency of any cell = Total of that cells row * Total of the cells column / Grand total
The expected frequency of Blue eyes and Black Hair = 37 * 34 / 74
= 17
The answer is option ( b)

In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Question: Two individuals, who are both heterozygous for eye and hair color, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring if the genes are unlinked? A) 9/16 will have brown eyes and red hair B) 9/16 will have blue eyes and red hair...

Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...
