Across
  1. 2. Made up of DNA and a basic and functional unit of heredity.
  2. 7. A position within a cistron occupied by mutation.
  3. 10. Sudden change in the genetic material where different alleles arise at the locus.
  4. 11. A term for traits that do not exhibit clear one-locus segregation.
  5. 13. It is a relationship between the two versions of a gene.
  6. 15. Located on a single chromosome where a series of allele can be found at linked loci.
  7. 19. Only one allele that occurs at a site or locus in the population.
  8. 20. Two alleles inherited for a particular gene and an individual’s collection of genes.
  9. 21. A pattern of any inheritance that doesn’t follow the Mendelian law of genetics.
  10. 24. It is where the intermediate inheritance for a specific trait is not completely expressed.
  11. 29. Have only one copy of a gene or DNA sequence in diploid cells.
  12. 30. Code for the same function or characteristics, as well as their impact that works together on the phenotype.
  13. 31. Trait expressed only in the homozygote.
  14. 37. One of the several alternative forms of a gene.
  15. 38. It implies that objects or factors do not act independently.
  16. 40. Existence of two or more variants at significant frequencies in the population.
  17. 42. A gene or genes that has two identical alleles.
  18. 43. Express an associated trait and the proportion of individuals carrying a particular variant of a gene.
  19. 44. The common term for polymorphism where many alleles occur.
Down
  1. 1. Any trait that is expressed in heterozygote.
  2. 3. A gene or genes that has a different allele.
  3. 4. Two alleles that occurs at a site or locus which are common to single-nucleotide polymorphism (SNPs).
  4. 5. A variation in one gene that affects several different aspects of the phenotype.
  5. 6. Caused by variation at a single genetic locus; a monogenic character.
  6. 8. A segregation at a single locus
  7. 9. Determined by some unspecified combination of genetic and environmental factors.
  8. 12. A trait determined by the combined activity of a number of genetic loci.
  9. 14. Means “standing above” which is a quantitative trait that indicates non-additivity of the effects of genotype to the phenotype.
  10. 16. Found in the Nucleus that carries a long piece of DNA. Helps transmit the proper genetic information.
  11. 17. More logical term for polymorphism where many alleles occur.
  12. 18. Gives rise to “liability” to disease and is treated as a continuous phenotype.
  13. 22. A unique chromosomal location on which a particular trait resides.
  14. 23. A diagram that showcases a family tree where inheritance of a trait through several generations can be seen.
  15. 25. Changes in the structure or number of a chromosome and most are known as aneuploidies.
  16. 26. A relationship between a particular phenotype and one or more genotypes.
  17. 27. Alleles, More than two allelic forms were found and each allele causes different phenotype.
  18. 28. Normal process of cell division that usually generates daughter cells with both sets identical to parent cell.
  19. 32. A cell or organism’s observable characteristics.
  20. 33. Packaged DNA in a cell that consists of DNA and proteins that is found in eukaryotic cells.
  21. 34. Alteration of the growth properties of a normal eukaryotic cell, evolving into a tumor cell.
  22. 35. Used only to produce gametes.
  23. 36. Shows a cell sorted in order and arranged in pairs that summarizes the chromosome constitution of a cell.
  24. 39. Is the combination of alleles inherited for each individual parent of two or more loci is known.
  25. 41. When the heterozygote has an intermediate phenotype and the homozygote is more severely affected.
  26. 43. A binary disease phenotype that is transformed into a probit after the probability of being affected.
