Question
Chapter 26.1, Problem 1AQTC
Summary Introduction
To analyze:
The consequence of unintentional breaks in DNA sequences other than the target sequence due to CRISPR.
Introduction:
CRISPR or Clustered Regularly Interspaced Short Palindromic Repeats are DNA sequences present in prokaryotes. They along with the enzyme Cas9 are part of the defense system of prokaryotes. Now, the CRISPR-Cas9 system is used as a gene-editing tool. It can break DNA strands at the desired location where the gene sequence can be modified according to our requirement.

3.
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.

Investigation: Is a dog more closely related to a coyote or a wolf?
Gray Wolf
Species Name: Canis lupus
Color: Light gray to black
Size: 80-120 pounds, 2.5 feet tall
Appearance: broad snout, round ears, long tail
Coyote
Species Name: Canis latrans
Color: Light gray to brown
Size: 20-50 pounds, 1.5 feet tall
Appearance: narrow snout, pointed ears, long tail
Dog, Alaskan Malamute
Species Name: Canis lupus familiaris
Color: Gray and white or brown and white
Size: 70-80 pounds, 2 feet tall
Appearance: broad snout, round ears, long tail
1. Examine the images and descriptions above.
Underline any similarities between the dog and the wolf.
Place a star
next to any coyote traits that are similar to the dog.
2. Based on appearance alone, which do you think is the most closely related to a dog?
