Worked Solution & Example Answer:A student constructed a model of the phases of meiosis in an organism with six chromosomes in its somatic cells - HSC - SSCE Biology - Question 17 - 2022 - Paper 1
Step 1
B. Chromosomes of matching size and structure are not paired.
Answer
In a properly constructed model of meiosis, homologous chromosomes must pair during the prophase I stage. In this case, the model shows chromosomes, but they are not paired correctly based on the information provided. Each pair of homologous chromosomes should consist of chromosomes with similar size and structure, which is essential for genetic recombination. Therefore, this option correctly indicates an error in the model.
