  2. 6. traits-individuals who are diploid for that trait have two alleles, getting one copy of their genome from each parent
  3. 7. selection-the process through which populations of living organisms adapt and change.
  4. 8. the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level
  5. 14. the ability to do work
  6. 15. process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA
  7. 18. group of individuals related by blood or marriage or by a feeling of closeness.
  8. 19. an evolutionary tree that diagrams the ancestral relationships among organisms.

  1. 1. the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
  2. 2. helix-term used to describe the physical structure of DNA.
  3. 4. early developmental stage of an animal while it is in the egg or within the uterus of the mother
  4. 5. process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells
  5. 9. A taxonomic rank used in classifying organisms, generally below the class, and comprised of families sharing a set of similar nature or character.
  6. 10. an individual who carries one deleterious allele for an autosomal recessive disorder
  7. 11. a compact mass of fungal hyphae producing perithecia or pycnidia.
  8. 12. circumstance where the expression of one gene is modified (e.g., masked, inhibited or suppressed) by the expression of one or more other genes
  9. 13. a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank
  10. 16. a type of allele which will not be manifested in an individual unless both of the individual's copies of that gene have that particular genotype.
  11. 17. polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid
