5 Matching questions

  1. Trait
  2. What did Gregor Mendel contribute to what we know about genetics?
  3. How can we use probability to predict traits?
  4. What does dominant mean?
  5. How many alleles for a particular trait do pea plants inherit from each parent?
  1. a The trait is visible whenever a dominant allele is present in the genotype such as TT or Tt(both tall)
  2. b Punnett squares use probability to predict the combinations of alleles in a genetic cross.
  3. c There is only one allele for a particular trait.
  4. d specific characteristic of an individual
  5. e Mendel's principles of heredity form the basis of modern genetics.

5 Multiple choice questions

  1. meiosis I results in two haploid daugther cells, each with half the number of chromosomes as the original cell
  2. The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and so two complete sets of genes.
  3. Codominance
  4. An individual's unique characteristics are determined by factors that are passed from parent to offspring.
  5. A polygenic trait is a trait that is contolled by two or more genes and produce a wide range of possible phenotypes.

5 True/False questions
