Download Inheritance and biotechnology assessment statements

Topic 3.4, 3.5, 10.2, 10.3
Write assessment statement and number in one color, write your answer in another color
Include all vocabulary terms in your answers. Diagrams and tables are great
Leave space to add additional information later
Each assessment statement should be about ½ to 1 full page.
Topic 3.4 Inheritance SL
3.4.1 State that the fusion of gametes results in diploid zygotes with two alleles of each gene that may be the same allele or different
alleles.
3.4.2 Distinguish between simple dominance and co-dominance in terms of alleles and their effects using named examples
3.4.3 List and describe with a named example each of the methods of inheritance(blood types, color blindness, hemophilia, cystic fibrosis,
Huntington’s disease, widow’s peak, down’s syndrome)
3.4.4 Analyze a pedigree to deduce the pattern of inheritance of genetic diseases. (sex linked dominant, sex linked recessive, autosomal
dominant, autosomal recessive)
Topic 3.5 Genetic modification and biotechnology
3.5.1 Explain the process of DNA profiling including the processes of PCR and gel electrophoresis
3.5.2. Describe the process of cloning using one parent cell
3.5.3 Compare benefits and problems of genetic modification of species
3.5.4 Discuss the risk to monarch butterflies of Bt crops
Topic 10.2 Inheritance HL
10.2.1 State that gene loci are said to be linked if on the sae chromosome
10.2.2 State that unlinked genes segregate independently as a result of peiosis
10.2.3 Compare variations within species as either discrete or continuous (discuss polygenic characteristics in this topic)
10.2.4 Analyze data using chi-squared test to determine whether the difference between an observed and expected frequency distribution
is statistically significant.
10.2.5 Calculate the predicted genotypic and phenotypic ratio of offspring of dihybrid crosses involving unlinked autosomal genes
10.2.6 Identify recombinants in crosses involving two linked genes.
Topic 10.3 Gene Pools and Speciation HL
10.3.1 Define gene pool
10.3.2 State evolution requires that allele frequencies change with time in populations
10.3.3 Compare types of reproductive isolation in populations
10.3.4 Compare the theories of evolution using punctuated equilibrium and gradualism
