18 Questions
What is cloning in the context of biology?
Creating genetically identical copies of an organism
Which method is used in plant cloning to produce clones by taking a section of the stem?
Cuttings
What is the purpose of embryo transplants in animal cloning?
To produce clones using egg and sperm cells
What happens when plant cells are placed in a growth medium with nutrients and hormones during tissue culture?
They grow into new plants that are genetically identical to the parent
How are genetically identical clones produced using embryo transplants in animals?
By transferring egg and sperm cells from parents with desirable traits
Which method of plant cloning is important for preserving rare plant species or commercial use in plant nurseries?
Tissue culture
What is the main difference between meiosis and mitosis?
Meiosis forms four non-identical cells, while mitosis forms two identical cells.
What is the ploidy level of gametes?
Haploid
How do gametes contribute to genetic variation in offspring?
Gametes contain a mixture of shuffled chromosomes.
What is the role of mitosis in the process of reproduction?
Mitosis generates many copies of cells.
Which method of reproduction leads to differentiation of cells?
Sexual reproduction
Why are the advantages of sexual reproduction considered the disadvantages of asexual reproduction?
Sexual reproduction results in genetic variation.
What is the main difference between cloning in the lab and adult cell cloning?
Cloning in the lab produces genetically identical offspring, while adult cell cloning results in clones of the adult body cell.
What is the process of adult cell cloning?
Extracting an adult body cell nucleus and placing it in an unfertilized egg cell.
What is a potential benefit of adult cell cloning?
Aid in research on embryo development.
Why does cloning through adult cells reduce the gene pool diversity?
It creates offspring with the same genetic information as the adult body cell.
What is a major risk associated with clones according to the text?
Low survival rate and potential genetic issues.
How can adult cell cloning potentially benefit extremely endangered species?
By helping to bring back species that have become extinct.
Test your knowledge on cloning techniques such as embryo cloning and adult cell cloning. Learn how embryos are fertilized in a lab and how adult cell cloning can produce genetically identical offspring. Explore the process of removing and transferring cell nuclei in cloning.
