Behavioral Objectives - Delta
  1. Write out a short explanation of the chromosome theory in relation to gene transfer and gene regulation. 
  2. List the number of chromosomes which are found in the following: human sperm cell, human egg cell, human zygote. Identify these as diploid or haploid cells.
  3. Contrast between genes and alleles and identify them in relation to a chromosome. 
  4. Identify and give examples of: homozygous alleles, heterozygous alleles; dominant allele, recessive allele; complete dominance incomplete dominance. 
  5. Explain and contrast between following terms:  genotype, phenotype; monohybrid cross, dihybrid cross; parental generation (P1), first generation (F1), second generation (F2); true-breeding, back-cross. 
  6. Given the phenotype of an individual and an indication of its homozygous or heterozygous condition, be able to determine its genotype using upper case  and lower case letters. 
  7. Given the genotype of an organism, determine the  possible genotypes of its gametes (egg or sperm).. 
  8. Solve monohybrid problems using Punnett squares (complete dominance and incomplete dominance). 
  9. When working a monohybrid problem, calculate the ratio and fraction of offspring likely to possess a given phenotype or genotype. 
  10. Given information concerning the offspring (phenotype and number) formed, you should be able to determine the genotypes and phenotypes of the parents. 
  11. Explain the differences between codominance and incomplete dominance.
  12. Explain and give an example of multiple alleles for a single gene. 
  13. Work genetic problems involving ABO blood groups. 
  14. Explain and demonstrate the inheritance of sex in mammals and insects (Drosophila). Contrast between autosomes and sex chromosomes. 
  15. Work genetic problems involving sex-linked inheritance for traits such as color blindness, hemophilia, and red eye color in Drosophila. 
  16. Diagram using XX and XY notation   male and female chromosome patterns  in humans. 
  17. Explain and identify examples of dihybrid crosses. Determine the genotypes for the gametes formed involving a dihybrid problem.
  18. Solve dihybrid problems using Punnett squares. Calculate the ratio and fraction of offspring likely to posses a given phenotype or genotype when solving the problem. Given information concerning the offspring (phenotype and number) formed, you should be able to determine the genotypes and phenotypes of the parents.
  19. Explain and list  examples of polygenic inheritance (multiple genes) and  epistasis. 
  20. Solve problems involving polygenic inheritance and epistasis. Given the genotypes and phenotypes of parents you should be able to determine the phenotype of the offspring in the correct ratio. 
  21. Explain the inheritance patterns of genes located on the same chromosome.
  22. Given the genes linked on a chromosome for a normal diploid cell, determine the genotype of the sperm or egg formed when crossing over occurs and when crossing over does not occur .  Using the Punnett square determine the offspring's phenotype formed by these linked genes  formed by the noncross-overs and cross-overs.
  23. Identify the following human traits as autosomal dominant or recessive; sex-linked dominant or recessive:

    24.          Albinism, Sickle-Cell Anemia, Huntington Disease, Hemophilia     
     
  24. Look up in an outside source, characteristics for Tay Sachs and PKU.
  25. Define nondisjunction. Indicate the reslult of nondisjunction of sex chromosomes and autosomes during meiosis.
  26. Describe the characteristics of an individual with Turner syndrome, Klinefilter syndrome, Trisomy X, and Trisomy 21 (Down syndrome).

    27. In general list the rate of incidence for each of these syndromes.
  27. Be able to analyze the information given in a pedigree. Examine the pedigrees shown in Figures 12-17 and 12-18.
