Question

question 1 - 8
manuel is a member of the science team at his school. during a competition, he is required to match a process with a description of the process. which of the following is the correct match of a process
and a phrase that describes the process?

inversion - produces diploid cells
crossing - over - produces haploid cells

non - disjunction - homologous chromosomes separating during meiosis
independent assortment - random arrangement of pairs of chromosomes during meiosis

Explanation:

Step1: Analyze the options

• Mitosis: Produces diploid cells, not meiosis. So the first option is wrong.
• Crossing - over: Occurs during meiosis and involves the exchange of genetic material between homologous chromosomes, not producing haploid cells. Haploid cells are produced by meiosis (reductional division).
• Non - disjunction: Refers to the failure of homologous chromosomes or sister chromatids to separate properly during cell division (mitosis or meiosis), not homologous chromosomes separating during meiosis (which is normal in meiosis I).
• Independent assortment: During meiosis I, pairs of homologous chromosomes (tetrads) are arranged randomly at the metaphase plate. This random arrangement of pairs of chromosomes is called independent assortment.

Answer:

Independent assortment - random arrangement of pairs of chromosomes during meiosis.
