Question

which events happen in meiosis that do not occur in mitosis? check all that apply.
check all that apply
the nuclear envelope is not visible in metaphase.
crossover occurs.
spindle fibers form
homologous chromosomes line up in pairs at the equatorial plate.
daughter cells form that are identical to each other and the original cell

Explanation:

• Crossover: Occurs in meiosis (prophase I) as homologous chromosomes exchange genetic material. Not in mitosis.
• Homologous chromosomes line up in pairs: In meiosis (metaphase I), homologous pairs align. In mitosis (metaphase), individual chromosomes align.

Other options:

• Nuclear envelope breakdown (metaphase) occurs in both.
• Spindle fiber formation occurs in both.
• Daughter cells identical (mitosis outcome). Meiosis produces non - identical cells.

Answer:

• B. Crossover occurs
• D. Homologous chromosomes line up in pairs at the equatorial plate
