Across
  1. 1. combination of alleles that an individual inherits for a given gene
  2. 8. science of heredity, or how traits are passed from parents to offspring
  3. 9. coiled structure made of DNA and protein that is present during cell division and visible with a light microscope
  4. 10. an individual living thing
  5. 12. a segment of DNA that carries the genetic code to make a specific polypeptide chain
  6. 13. DNA and RNA
  7. 14. one of two or more different versions of the same gene
Down
  1. 2. result of a reproductive process; children
  2. 3. allele that is masked by the presence of another allele for the same gene when they occur together in a heterozygote
  3. 4. referring to an allele that is masked by the presence of another allele (called dominant) for the same gene when both are present in a heterozygote; or referring to a trait controlled by such an allele
  4. 5. characteristics of an organism that depend on how the organism’s genotype is expressed, such as purple or white flowers
  5. 6. allele that masks the presence of another allele for the same gene when they occur together in a heterozygote
  6. 7. double-stranded nucleic acid that stores genetic information; also known as deoxyribonucleic acid
  7. 11. Austrian monk who lived in the 1800s and discovered the laws of inheritance by careful, repeated experiments with pea plants; called the “father of genetics”
