  1. 2. a cross in which an experimenter crosses an individual that is heterozygous for two genes to an individual that is homozygous recessive for the same two genes.
  2. 12. the first generation in an experiment; true breeding with regards to a particular trait
  3. 14. describes a diploid individual that has two identical alleles of a particular gene.
  4. 17. a hypothesis that assumes there is no real difference between the observed and expected values.
  5. 19. a cross in which an experimenter is following the outcome of only a single trait
  6. 23. the degree to which the observed data and expected data are similar to each other. If the observed and predicted data are very similar, the goodness of fit is high.
  7. 24. a segment of DNA that produces of functional product
  8. 25. an individual produced from a single-factor cross in which the parents had different variants for a single character.
  9. 26. a hybrid that is heterozygous for alleles of two different genes.
  10. 27. chart representing family relationships.
  11. 29. describes an allele that determines the phenotype in the heterozygous condition.
  12. 30. the genetic composition of an individual, especially in terms of the alleles for particular genes.

  1. 1. the deviation between the observed and expected outcomes due to chance
  2. 3. a cross in which an experimenter follows the outcome of two different traits.
  3. 4. in a statistical analysis, the number of categories that are independent of each other.
  4. 5. a diagrammatic method in which the gametes that two parents can produce are aligned next to a square grid as a way to predict the types of offspring the parents will produce and in what proportions.
  5. 6. in a chi square table, the probability that the deviations between observed and expected values are due to random chance.
  6. 7. the chance that an event will occur in the future
  7. 8. describes a diploid individual that has different versions (i.e., two different alleles) of the same gene.
  8. 9. the mating of two organisms of the same species with different characteristics
  9. 10. gene combination formed after recombination i.e different combination of genes than present in parents
  10. 11. hybridization the mating of two organisms of the same species with different characteristics true-breeding line a strain of a particular species that continues to produce the same trait after several generations of self-fertilization (in plants) or inbreeding
  11. 13. the offspring produced from a cross of the parental generation
  12. 15. alternative versions of a specific gene
  13. 16. a trait or gene that is masked by the presence of a dominant trait or gene.
  14. 18. fertilization that involves the union of male and female gametes derived from the same parent.
  15. 20. a commonly used statistical method for determining the goodness of fit. This method can be used to analyze population data in which the members of the population fall into different categories.
  16. 21. an equation used to solve genetic problems involving two types of unordered events
  17. 22. the probability that two or more independent events will occur is equal to the products of their individual probabilities
  18. 28. the observable traits of an organism.
