Question

match each description or term to either mitosis or meiosis
homologues pair up
crossing over occurs
reduction division
makes exact genetic copies of cells
makes more somatic cells
only separates sister chromatids
separates members of the homologous pair and sister chromatids
makes gametes

Explanation:

• Homologues pair up: In meiosis, homologous chromosomes pair up during prophase I in a process called synapsis.
• Crossing over occurs: This is a key event in meiosis that happens during prophase I when homologous chromosomes exchange genetic material.
• Reduction Division: Meiosis is a reduction - division process as it reduces the chromosome number by half.
• Makes exact genetic copies of cells: Mitosis results in two daughter cells that are genetically identical to the parent cell.
• Makes more somatic cells: Mitosis is responsible for the growth and repair of somatic (body) cells.
• Only separates sister chromatids: In mitosis, sister chromatids separate during anaphase.
• Separates members of the homologous pair and sister chromatids: Meiosis involves the separation of homologous chromosomes in meiosis I and sister chromatids in meiosis II.
• Makes gametes: Meiosis produces gametes (sperm and egg cells).

Answer:

• Homologues pair up: MEIOSIS
• Crossing over occurs: MEIOSIS
• Reduction Division: MEIOSIS
• Makes exact genetic copies of cells: MITOSIS
• Makes more somatic cells: MITOSIS
• Only separates sister chromatids: MITOSIS
• Separates members of the homologous pair and sister chromatids: MEIOSIS
• Makes gametes: MEIOSIS
