- 31. The genetic makeup of an organism •The two alleles inherited for a particular gene
- 32. a taxonomic group that includes multiple species that are closely related and share common characteristics
- 33. Differences in the sequences of genes between individuals. This is what makes organisms of the same species look different from each other.
