Summary Introduction
To determine:
The interaction of the endocrine system and the nervous system.
Concept introduction:
The nervous system and endocrine system coordinate along with the body. The endocrine system secretes hormones that co-ordinate slower but longer-acting responses including reproduction, development, energy

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?
