1 WLHS / Biology / Monson Name Date Per FINAL EXAM STUDY GUIDE: BIOLOGY - Semester 2 UNIT 6 - Chapters 11 & 14: GENETICS, HEREDITY, MENDEL, HUMAN GENETICS VOCABULARY (CH 11): Traits Gamete Fertilization Hybrid Allele Dominant Recessive Law of segregation Phenotype Genotype Homozygous Heterozygous Monohybrid cross Dihybrid cross Punnett square Diploid Haploid Homologous chrom. Meiosis Zygote Crossing over Nondisjunction Sperm vs. egg Law of independent assortment VOCABULARY (CH 14): Pedigree Carrier Fetus Cystic fibrosis Tay-Sachs disease Phenylketonuria (PKU) Huntington s disease Incomplete dominance Codominance Multiple alleles Autosome Sex chromosome Sex-linked trait Polygenic inheritance ABO blood groups Hemophilia Down Syndrome Karyotype MEIOSIS: 1) Compare the processes of MITOSIS and MEIOSIS: How many daughter cells are produced? If the parent cell has 22 chromosomes, how many chromosomes are in the daughter cells produced? Are cells produced diploid or haploid? Does crossing over occur? If crossing over does occur, WHEN does it happen? What is the reason or purpose for producing the daughter cells? (what are the daughter cells used for?) How similar are the daughter cells to each other? How many phases are in each process? (list them) MITOSIS MEIOSIS WHERE in an animal s body does this process occur? 2) More MEIOSIS questions: GENETICS: what happens during crossing over? in what phase do the homologous pairs of chromosomes separate? in what phase do the sister chromatids separate from each other in MEIOSIS? # of chromosomes in human somatic (body) cell? # of chromosomes in human gamete? 3) Cross two plants that are heterozygous for green pods. List all possible GENOTYPES and PHENOTYPES in the offspring. (Hint: green pod color, G, is dominant over yellow pod color, g). offspring genotypes: offspring phenotypes:

2 4) You are continuing your study of pea plants and will now conduct a DIHYBRID cross. In addition to the pod color trait in the previous problems (green is dominant to yellow), you also know that tall plants are dominant over short plants. Cross 2 plants, both of which are heterozygous green pod color and heterozygous tall. CROSS: X. List the 4 gamete combinations possible in each parent: What is the phenotypic ratio of the offspring? (list below): EXCEPTIONS TO MENDEL: 5) For each example below, choose from the following answers: Incomplete Dominance Sex-Linked Multiple Alleles Codominance human blood types a blue flower and a yellow flower plant are crossed; the offspring are green a red flower and white flower are crossed; the offspring are red w/ white spots men get hemophilia more often than women 6) A mother with blood type A and a father with blood type B have a child with blood type O. Complete the Punnett Square to show how this could happen. 7) A couple who both are normal have a son with hemophilia. Complete a Punnett Square to show how this could happen. **Hemophilia is sex-linked & recessive! 8) A red cow and a white bull are crossed to produce roan offspring (both white and red hairs). Complete a Punnett Square to show how this could happen. 9) KARYOTYPE: Look at the karyotype shown here. What is the sex of this person? What chromosomal abnormality do they have? What is the cause of this abnormality and when does it happen? How many chromosomes does a normal karyotype have? ***Be able to interpret a PEDIGREE; Review your notes and Genetics study guide!
