  1. 4. a genetic variant that masks the presence of a recessive allele
  2. 5. A variant form of a gene, representing different versions of a DNA sequence and its traits
  3. 6. A segment of DNA that acts as the basic unit of heredity
  4. 7. A genetic alteration that changes a single nucleotide but does not alter the resulting amino acid sequence
  5. 9. An individual's individual genetic makeup
  6. 10. 2 different alleles for a specific gene
  7. 11. A permanent alteration in an organism's DNA sequence
  8. 12. physical expression of traits
  9. 14. The entire set of genetic instructions (DNA) found in a cell
  10. 15. Thread-like structure made from coiled DNA found in the nucleus
  11. 16. A type of mutation where a single nucleotide base is replaced by a different base
Down
  1. 1. A genetic alteration where a DNA change creates a premature stop codon in the amino acid sequence
  2. 2. A type of mutation that is caused by insertion or deletion
  3. 3. A genetic alteration of adding 1 or more nucleotides, changing the DNA sequence
  4. 8. A genetic alteration of losing 1 or more nucleotides, changing the DNA sequence
