6 Written questions

6 Multiple choice questions

  1. the first generation of offspring obtained from an experimental cross of two organisms
  2. describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes (brown eyes)
  3. a condition in which a trait in an individual is intermediate between the phenotype of the individual's two parents because the dominant allele is unable to express itself fully (different dominance)
  4. describes an individual that has identical alleles for a trait on both homologous chromosomes (both alleles are alike)
  5. a cross between individuals that have different alleles for the same gene (two characteristics are tracked)
  6. a graphic used to predict the results of a genetic cross (predict the offspring)

6 True/False questions

  1. F2 Generationthe first generation of offspring obtained from an experimental cross of two organisms

          

  2. Phenotypean organism's appearance or other detectable characteristic that results from the organism's genotype and the environment

          

  3. P Generationparental generation, the first two individuals that mate in a genetic cross (parents)

          

  4. True-Breedingdescribes a trait or an allele that is expressed only when two recessive alleles for the same characteristic are inherited (blue eyes, shows up in the F2 generation)

          

  5. Recessivethe entire genetic makeup of an organism; also the combination of genes for one or more specific traits (uses letters in problems)

          

  6. Monohybrid Crossa cross between individuals that involves one pair of contrasting traits
