during prophase i of meiosis,

there are four haploid daughter cells.

chromosome pairs are positioned in the middle of the cell.

the homologous chromosomes separate and move towards opposite poles.

homologous chromosomes stick together in pairs.

there are two daughter cells, each with 23 chromosomes.

Explanation:

1. Analyze each option:

• Option 1: Four haploid daughter cells are the result of telophase II of meiosis, not prophase I. So this is incorrect.
• Option 2: Chromosome pairs being positioned in the middle of the cell occurs during metaphase I, not prophase I. So this is incorrect.
• Option 3: Homologous chromosomes separating and moving to opposite poles happens during anaphase I, not prophase I. So this is incorrect.
• Option 4: During prophase I of meiosis, homologous chromosomes (each consisting of two sister chromatids) pair up, a process called synapsis. So this option correctly describes an event in prophase I.
• Option 5: Two daughter cells with 23 chromosomes (in humans) are the result of telophase I and cytokinesis I, not prophase I. So this is incorrect.

Answer:

D. homologous chromosomes stick together in pairs.
