CHARACTERISTICS OF LIFE:
What are the 8 characteristics of life? Give an example of each.
Draw the stages of mitosis, and label each stage. Briefly explain what is occurring in each stage of mitosis101. Prophase 102. Metaphase 103. Anaphase 104. Telophase
Draw the stages of meiosis, and label each stage. Briefly explain what is occurring in each stage of meiosis.105. Prophase I 106. Metaphase I 107. Anaphase I 108. Telophase I
109. Prophase II 110. Metaphase II 111. Anaphase II 112. Telophase II
Complete the following table below comparing and contrasting Mitosis and Meiosis (pg 275 in your book):

SpongeBob’s aunt and uncle, SpongeWilma and SpongeWilbur, have the biggest round eyes in the family. Wilma is believed to be heterozygous for her round eye shape, while Wilbur’s family brags that they are a pure line. Complete the Punnett square to show the possibilities that would result if SpongeWilma and SpongeWilbur had children.
146. Give the genotype for each person. Wilma - _______ Wilbur - ________
147. Complete a Punnett square to show the possibilities that would result if they had children.
148. List the possible genotypes and phenotypes for the kids.
149. What is the probability that the kids would have round eyes? ____ %
150. What is the probability that the kids would be oval eyes? ____ %
151. SpongeBob’s mother is so proud of her son and his new wife, SpongeSusie, as they are expecting a little sponge. She knows that they have a 50% chance of having a little roundpants, but is also hoping the new arrival will be blue (a recessive trait) like SpongeSusie and many members of her family. If SpongeBob is heterozygous for his yellow body color, what are the chances that the baby sponge will be blue? Create a Punnett square to help you answer this question.
