Across
  1. 14. an extent at which a particular genotype is expressed in a person, e.g. a severity of a disease
  2. 15. complete set of DNA of an organism
  3. 17. observable traits of an individual (hair color, blood type etc...)
  4. 19. a process by which information from a DNA molecule is copied on an RNA
  5. 21. Only one allele is present within the set of chromosomes
  6. 22. a repetitive sequence of DNA at the both ends of a chromosome
Down
  1. 1. a region on chromosomes to which microtubules attach during mitosis
  2. 2. one gene contributes to multiple phenotypic effects, e.g., affects multiple organ systems
  3. 3. an alternative DNA sequences at a particular locus
  4. 4. The two homologous chromosomes contain identical alleles at a given locus
  5. 5. location of a gene on a chromosome
  6. 6. one of the two identical copies of a chromosome resulting from DNA replication
  7. 7. an allele that is expressed phenotypically both in homozygous and heterozygous states
  8. 8. an allele that is expressed phenotypically only in homozygous state
  9. 9. when both alleles influence the phenotype equally (e.g. Blood type AB)
  10. 10. a protein complex at a centromere to which microtubules attach during mitosis.
  11. 11. a process of a templated polymerization during which DNA molecule is copied
  12. 12. a segment of DNA molecule with a nucleotide sequence encoding RNA.
  13. 13. The two homologous chromosomes each contains a different allele at a given locus
  14. 16. a complex of DNA and proteins during interphase
  15. 18. genetic composition of an individual
  16. 20. the probability that a person with a particular genotype will manifest it phenotypically
  17. 23. any alteration in a genome of a cell
