G10 - 12.4 Meiosis

How many sets of genes are found in most adult organisms?

• Four sets

• Three sets

• Two sets

• One set

What is the haploid number of chromosomes in human gametes?

• 12 chromosomes

• 46 chromosomes

• 23 chromosomes

• 78 chromosomes

What is the end product of meiosis?

• Three daughter cells

• Two daughter cells

• Four daughter cells

• One daughter cell

During which phase of meiosis does crossing-over occur?

• Meiosis I

• Meiosis II

• Telophase I

• Prophase II

What is the main difference between meiosis and mitosis?

• Meiosis produces two cells

• Mitosis involves crossing-over

• Meiosis produces four cells

• Mitosis results in haploid cells

What happens to homologous chromosomes during meiosis I?

• They separate and move to the poles

• They duplicate

• They cross over

• They remain together

What is the term for alleles of different genes being inherited together?

• Allelic variation

• Gene linkage

• Chromosome duplication

• Genetic drift

What occurs during anaphase II of meiosis?

• Crossing-over happens

• Homologous chromosomes align

• Sister chromatids separate

• Nuclear envelope forms

What is the function of telomeres?

• To create genetic variation

• To protect chromosome ends

• To separate chromatids

• To form spindle fibers

What is the main purpose of meiosis?

• To repair DNA

• To duplicate chromosomes

• To create genetic diversity

• To produce identical cells
