Across
- 6. the physical appearance of a trait (blue eyes)
- 8. this means the gene has two different alleles (Rr or Pp)
- 9. the genetic makeup of an organism shown as letters (BB or Bb)
Down
- 1. the passing of traits from parent to offspring
- 2. this means the gene has two copies of the same allele (RR or rr)
- 3. the study of genes, heredity and genetic variation in living things
- 4. different forms of the same gene (letters)
- 5. an allele shown using a capital letter that is strong and hides recessive alleles
- 7. an allele shown using a lower case letter that is weak and can only be seen if inherited from both parents
