Practise MYP Biology questions on 9.2 Cloning and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Why is Somatic Cell Nuclear Transfer (SCNT) a more precise method than embryo splitting for replicating an animal with specific desirable traits?
True or False: Observations of Dolly the sheep suggest that cloned animals may face increased risks of premature aging and health issues.
Why is the high cost of cloning considered a significant disadvantage for its widespread use in agriculture?
Vegetative propagation is a natural cloning process that occurs when new plants develop from:
What potential health risk was specifically observed in Dolly the sheep, leading to concerns about the long-term health of cloned animals?
SCNT produces a larger number of offspring per procedure
Embryo splitting requires a sterile laboratory while SCNT does not
SCNT is a natural process while embryo splitting is entirely artificial
SCNT uses DNA from an animal whose adult traits are already known
True
False
It is a complex and resource-intensive process
It requires the use of expensive transgenic seeds
It requires the purchase of new zygotes for every generation
Cloned animals require more food than naturally bred animals
Non-reproductive tissues such as stems, leaves, or roots
The fusion of male and female gametes
Spores produced in the sori
Seeds dispersed by wind or water
Inability to digest milk
Loss of skin pigmentation
Resistance to antibiotics
Premature aging and health problems
