Meiosis, Stem Cells, and DNA Fingerprinting

What is the primary purpose of meiosis in organisms?

• To produce identical cells

• To repair damaged tissues

• To generate genetic diversity in gametes

• To create somatic cells

Which of the following is a key feature of stem cells?

• They can only differentiate into one type of cell

• They have a limited number of cell divisions

• They can differentiate into many types of cells

• They do not have the ability to self-renew

What is DNA fingerprinting primarily used for?

• To determine blood type

• To identify genetic diseases

• To identify individuals or their genetic relationships

• To enhance DNA replication speed

During which phase of meiosis do homologous chromosomes separate?

• Anaphase I

• Anaphase II

• Telophase I

• Telophase II

What type of cells are produced at the end of meiosis?

• Diploid cells

• Haploid cells

• Triploid cells

• Tetraploid cells

Which of the following is NOT a characteristic of stem cells?

• Ability to differentiate into various cell types

What is the significance of crossing over in meiosis?

• It decreases genetic variation

• It repairs DNA errors

• It increases genetic variation
