Across
- 3. different versions of the same gene. e.g. Hair colour gene can be a ginger allele or brown allele
- 5. the alleles present in an individuals genetic make up e.g. BB or Bb or bb
- 6. allele is only expressed if dominant allele isn’t present in the genotype
- 8. two identical alleles e.g. BB or bb
Down
- 1. A small section of DNA that controls an inherited characteristic. e.g. hair colour or eye colour gene.
- 2. –two different alleles e.g. Bb
- 4. the characteristic that is expressed e.g. Ginger hair, blue eyes, tongue rolling
- 7. the allele is expressed if present
