Presentation Transcript

  1. What does this picture show? • What does “46” stand for? • How many parent(s) cell(s) and daughter cells? • Compare & Contrast parent and daughters genome • What type of reproduction do you recognize in this illustration?

  2. Parent cell Parent cell divide through asexual reproduction, 1. Which diagrams best illustrate the daughter cells that result from normal mitotic cell division of this zygote? 2. Explain

  3. Describe illustration A & B • Which method shows asexual reproduction? • How do you know? • Compare & Contrast method A & B

  4. 1. How many chromosomes would a sperm or an egg contain if either one resulted from the process of mitosis? 2. If a sperm containing 46 chromosomes fused with an egg containing 46 chromosomes, how many chromosomes would the resulting fertilized egg contain? Do you think this would create any problems in the developing embryo? 3. In order to produce a fertilized egg with the appropriate number of chromosomes (46), how many chromosomes should each sperm and egg have?

  5. Label as diploid or haploid

  6. Label as diploid or haploid
