Extra Credit (due no later than Wednesday, February 13)

Create a graph to illustrate the number of chromosomes found in the animals we saw in Charlotte's Web. Remember to include, labels for the x- and y-axis, an informational title, and your name as the "source." You don't need a legend.
Horse 64
Pig 38
Cow 60
Sheep 54
Goose 78 (estimate)
Barn Spider 24 (estimate)

Answer the following questions usiing the graph you create.
1) Which animals on the graph is considered the most and least intelligent? (Hint: You may have to do some research.)
2) Based on your answer to #1, does there seem to be any relationship between chromosome number and intelligence? Why or why not?
3) Which animal has a chromosome number that most closely resembles that of humans?
4)Why don't any of the animals have an odd number of chromosomes?
5) What is the diploid number of chromosomes for cows?
6) What is the haploid number of chromosomes for horses?
