- 9. have 2 different alleles
- 10. physical expression of a gene
- 11. expressed when in presence of a recessive allele
- 12. inherited characteristics
Down
- 1. genetic makeup in letters
- 2. hidden when with a dominant allele
- 3. different forms of a gene
- 5. have 2 of the same allele
- 7. both alleles of a gene pair in a heterozygote are fully expressed
