  4. d a gene that has more than two alleles
  5. e Spindle fibers attach to the chromosomes

5 Multiple choice questions

  1. The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and so two complete sets of genes.
  2. Situation in which the phenotypes produced by both alleles are completely expressed
  3. separation of alleles

  5. having two identical alleles for a trait

5 True/False questions

  1. If an offspring is homozygous recessive, what do you know about the parents?The offspring recieved one recessive allele from each parent.


  2. What is the reason for codominance?The phenotypes for both alleles are equally expressed in the offspring.


  3. Define homologous chromosomesChromosome pairs of the same length, centromere positions, and staining patterns for the same characteristics.


  4. Where does an oganism get its unique characteristics?An individual's unique characteristics are determined by factors that are passed from parent to offspring.


  5. Define hybridA hybrid is the offspring that crosses between parents with different traits.
