Describe the importance of the ability of organisms to have offspring that are all different, and are different than their parents: 8. How many gametes does a parent cell produce in the process of Meiosis?_____ Evidence: 9. How many pairs of chromosomes does a normal cell contain? ______ “”a haploid cell contain?_____ “” a diploid cell contain?_____ Evidence: 10. The number of chromosomes in a gamete is _______ Evidence: 11. Show the cross of two pea plants that are homozygous for both pod color and pod shape, one parent dominant and one parent recessive.

If there were 300 offspring from the cross listed in number 12, list the number of offspring that would have a. Dominant phenotype for both pod color and pod shape______ b. Dominant phenotype for pod color and recessive phenotype for pod shape_____ c. Recessive phenotype for pod color and dominant phenotype for pod shape_____ d. Recessive phenotype for pod color and pod shape______ 14. Imagine that the traits for pod color and pod shape are BOTH on chromosomes number 10. Show the cross from question 12 again now knowing that these two traits are on the SAME chromosome.

NOW, imagine that we found out that the genes for pod shape and pod color are actually found on the X chromosome. Do this same cross one more time to show what the offspring would look like if these two genes are sex-linked.

For question number 12, describe the phenotypes of the offspring if the traits for Pod Color and Pod Shape were incompletely dominant rather than completely dominant.
