  1. 3. inherited traits are controlled by traits transmitted by gametes maintaining genetic continuity from generation to generation
  2. 5. All organisms are composed of basic structures called cells derived from pre-existing cells.
  3. 9. other term for Polygenic traits; governed by alleles at two or more loci, and each locus has some influence on the phenotype
  4. 10. viral DNA can't direct synthesis of particles; can be used to cut any organism’s DNA at specific nucleotide sequence producing reproducible set of segments
  5. 12. most famous case among royal families of Europe especially British monarchy
  6. 15. study of chromosome structure and abnormalities; used to predict certain genetic disorders especially among women who got pregnant late in life (detection of Down Syndrome)
  7. 16. small individual sitting on sperm; complete miniature adult
  8. 18. inheritance pattern that follows the laws of segregation and independent assortment in which a gene inherited from either parent segregates into gametes at an equal frequency
  9. 19. useful when studying any population when progeny data from several generations is limited; also and when studying species from long generation time and low fertility rate
  10. 20. expressed even if it is paired with a recessive allele
  11. 21. cloning technique; taking cell from adult sheep from mammary gland of adult sheep and removing genetic material then inserting genes to empty egg cell taken from another sheep
Down
  1. 1. literally means "good appearance" or "normal appearing", science of making phenotypic improvements to humans after birth, generally to affect a problematic genetic condition.
  2. 2. heritable change and source of genetic variation that we see among different species
  3. 4. structures such as organs are not originally present in embryo but formed from denovo (new) / assembled
  4. 6. location of a gene/marker on the chromosome
  5. 7. Study of the inheritance of phenotypic traits and variations patterns in populations
  6. 8. Greek word where Genetics was derived from
  7. 11. Classical investigative approach; study involves patterns on inheritance of traits
  8. 13. founder of Planned Parenthood; proponent of Negative Eugenics
  9. 14. branch of Biology concerned with the study of genes, genetic variation, and heredity in organisms
  10. 17. has small amount of genetic material so easy to manipulate and understand how genetic variation are being caused. Unlike bacteria, it mutates
