Worked Solution & Example Answer:Complete Figure 7 to show the chromosome content of the cells that would result from a normal meiotic division of the diploid parent cell shown in Figure 6 - AQA - A-Level Biology - Question 6 - 2018 - Paper 1
Step 1
Chromosome content after 1st division of meiosis
Answer
After the first division of meiosis, the diploid parent cell (2n) will divide into two haploid cells, each containing one long and one short chromosome. Therefore, the chromosome content after the first division will be:
- One cell: 1 long and 1 short chromosome (n)
- Another cell: 1 long and 1 short chromosome (n)
Step 2
Chromosome content of the four daughter cells
Answer
During the second division of meiosis, each of the two haploid cells will divide again into two, resulting in four daughter cells. The chromosome content of the four daughter cells will be:
- Daughter Cell 1: 1 long chromosome (n)
- Daughter Cell 2: 1 long chromosome (n)
- Daughter Cell 3: 1 short chromosome (n)
- Daughter Cell 4: 1 short chromosome (n)
Thus, the completed diagram for Figure 7 should depict: 1 long chromosome and 1 short chromosome in each of the four daughter cells.
