Textbook Question
Chapter 43, Problem 10TYPSS
Alzheimer’s disease is a common form of dementia affecting millions of people, especially the elderly. Two regions of the brain are particularly affected, often shrinking dramatically and accumulating large deposits of extracellular material. Based on your knowledge of memory, what two brain regions do you think these are? Explain.

In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white
flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with
orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which
produced the following results:
a.
b.
333 red fruit, yellow flowers
64 red fruit, white flowers
58 orange fruit, yellow flowers
350 orange fruit, white flowers
Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently. Make sure
to interpret the P value obtained from your chi-square test.
Calculate and provide the map distance (in map units) between the two genes.
