Lesson Worksheet: Meiosis Biology
In this worksheet, we will practice explaining the role of meiosis in the formation of gametes.
Q1:
A body cell in a giant panda has 42 chromosomes. How many chromosomes will be in a panda sperm cell?
Q2:
How many chromosomes are in a human gamete?
Q3:
After fertilization, a zygote is formed.
What type of cell division do cells in the zygote stage undergo to begin forming a new organism?
- AMitosis
- BMeiosis
Q4:
Which of the following is incorrect about meiosis and variation?
- AEach chromosome in a pair may contain different versions of the same gene.
- BMeiosis creates genetic variation because each gamete formed has a different set of chromosomes.
- CHaploid daughter cells are produced in meiosis as they have the full set of chromosomes to start dividing into a zygote.
- DIn the zygote, one chromosome in each pair comes from each parent.
- ESexual reproduction produces more variation in the offspring than asexual.
Q5:
Which of the following correctly defines a cell that is haploid?
- AA haploid cell contains one set of each unpaired chromosome.
- BA haploid cell contains half of each chromosome.
- CA haploid cell contains two sets of each paired chromosome.
- DA haploid cell contains three sets of each unpaired chromosome.
Q6:
A normal cell in a spinach plant has 12 chromosomes. How many chromosomes will be in the pollen grain?
Q7:
Which of the following statements best explains why it is important that gametes are haploid?
- ASo when they join in fertilization, the zygote has the correct haploid number
- BSo the gametes do not get confused with normal body cells
- CSo when they divide to form an embryo, the DNA does not have to be replicated
- DSo when they join in fertilization, the zygote has the correct diploid number
Q8:
For the following statements about meiosis, choose whether they are true or false.
Meiosis involves the parent cell dividing twice.
- AFalse
- BTrue
Meiosis produces daughter cells that are genetically identical to the parent cell.
- AFalse
- BTrue
Meiosis produces cells that are haploid.
- AFalse
- BTrue
Q9:
By what type of cell division are gametes formed in adults?
- AMitosis
- BMeiosis
Q10:
What is produced by a cell that has undergone meiosis?
- ATwo genetically different haploid cells
- BFour genetically identical haploid cells
- CFour genetically different haploid cells
- DTwo genetically identical diploid cells
- EFour genetically different diploid cells
