Mitosis & Meiosis: Thinking Scientifically

It takes 15 minutes for certain embryo cells to divide. How many cells

Answer:

would be produced from one cell after four hours? Hint: Start with one

cell at time zero, so after 15 minutes you would have 2 cells, etc.

Show your work: 4 hours = 16 divisions. 15 divisions after 1 cell  2 cells

Look at the body cell in figure 1 below to answer the questions.

1) How many chromosomes are in the body cell of the organism? 6

2) How many chromosomes would be in each gamete? 3

3) How many chromosomes would be in the fertilized egg of this gamete? 6

Figure 1: Example Cell

4) How many chromosomes would come from each parent? 3

5) Will every gamete contain identical chromosomes? Explain.

No. Some crossing over will occur that will blend parts of chromosomes.

Fill in the blanks based on your knowledge of mitosis and meiosis.

1. A human has 46 chromosomes in each body cell. How many chromosomes would be

found in its daughter cells after mitosis?

2. A yeast cell has 32 chromosomes. How many chromosomes would be found in its

daughter cells after meiosis?

3. A fruit fly’s gametes have

chromosomes, because its body cells have 4 chromosomes.

4. A kangaroo’s somatic cells have 12 chromosomes, so that means its sex cells have

chromosomes.

5. If cabbage plant has 9 chromosomes in its reproductive cells, then it means that it has 18

chromosomes in its

somatic

cells.

6. A fern has 600 chromosomes in its gamete cells. How many chromosomes would be

found in its regular body cells?

1,200
