IB Biology SL A3.1.9 Diversity of eukaryote genomes

IB Biology syllabusFirst assessment 2025
Practise interpreting gene-number tables across eukaryotes and judging what can, and cannot, be concluded from genome comparisons.
How this is tested
- interpret tables of estimated gene numbers without assuming evolutionary progress
- explain why gene number alone does not determine evolutionary success
- reject unsupported conclusions about relatedness or protein numbers from limited data
