Worked Solution & Example Answer:The table describes meiosis - OCR Gateway - GCSE Biology - Question 7 - 2020 - Paper 4

Step 1

Identify correct genetic description

96%

114 rated

Answer

Meiosis produces haploid cells, which means that these cells contain half the number of chromosomes compared to the parental diploid cells. Therefore, the correct rows must identify cells as 'haploid' where appropriate.

Step 2

Evaluate genetic variation introduced

99%

104 rated

Answer

Meiosis introduces genetic variation through processes such as crossing over and independent assortment of chromosomes. Rows that indicate no genetic variation (marked with 'x') are not correct.

Step 3

Determine type of cells made

96%

101 rated

Answer

Meiosis primarily produces gametes (sperm and egg cells) rather than body cells. Therefore, options A and B, which state 'body cells', are incorrect.

Step 4

Conclusion

Answer

Based on the above evaluation, the correct row in the table is row C, which indicates 'haploid' with genetic variation introduced, and identifies the cell type as 'gametes'.
