Presentation transcript:

Turn in your meiosis diagram, then title a new spiral page: Meiosis Questions Check your knowledge A17-21

Question 1: What is the purpose of meiosis?

Answer 1: What is the purpose of meiosis? To make reproductive cells

Question 2: How many new cells are made through the process of meiosis?

Answer 2: How many new cells are made through the process of meiosis? 4

Question 3: Where does a baby get it’s DNA from?

Answer 3: Where does a baby get it’s DNA from? From both of its parents

Question 4: Why do reproductive cells only have half the number of chromosomes as an organisms body cells?

Answer 4: Why do reproductive cells only have half the number of chromosomes as an organisms body cells? A baby gets half a set of chromosomes from each parent

Question 5: How many genes does a human have?

Answer 5: How many genes does a human have? About 50,000

Question 6: Why do siblings not look exactly the same even with the same parents?

Answer 6: Why do siblings not look exactly the same even with the same parents? They don’t get the exact same genes from their parents

Question 7: If a cell that has 16 chromosomes goes through meiosis, how many chromosomes will each of the new cells have?

Answer 7: If a cell that has 16 chromosomes goes through meiosis, how many chromosomes will each of the new cells have? 8

Question 8: What are the new cells made by meiosis called?

Answer 8: What are the new cells made by meiosis called? Daughter cells

Question 9: How many chromosomes does a human reproductive cell have?

Question 9: How many chromosomes does a human reproductive cell have? 23 chromosomes (because a human body cell has 46 chromosomes)

Question 10 Draw the process of meiosis for an organism with 4 chromosomes.

Answer 10 Draw the process of meiosis for an organism with 4 chromosomes.

So…. How did you do? 0 wrong: Awesome, you know your stuff! Keep it up! 1-2 wrong: Good job! Look over the questions you got wrong and make sure you understand them. 3-4 wrong: review your notes, better luck next time. 5 or more wrong: re-read the chapter and go over your notes again.
