6 Written questions

6 Multiple choice questions

  1. a cross between individuals that involves one pair of contrasting traits
  2. describes organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait (always produces offspring with the same trait)
  3. parental generation, the first two individuals that mate in a genetic cross (parents)
  4. the ratio of phenotypes produced by a cross
  5. describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes (brown eyes)
  6. a cross between individuals that have different alleles for the same gene (two characteristics are tracked)

6 True/False questions

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

          

  2. F1 Generationthe second generation of offspring, obtained from an experimental cross of two organisms; the offspring of the F1 generation

          

  3. Punnett Squarean organism's appearance or other detectable characteristic that results from the organism's genotype and the environment

          

  4. Complete dominancea relationship in which one allele is completely dominant over another

          

  5. Heterozygousdescribes an individual that has identical alleles for a trait on both homologous chromosomes (both alleles are alike)

          

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