Objectives for Exam 1 PCB 3063, Spring 2017 Mitosis and Meiosis (Lectures 1, Chapter 2) Of basic importance in this material is to know the essential differences between mitosis and meiosis, what
homologous chromosomes are and how they behave in mitosis and meiosis.   Understand the concept of the cell cycle and know what happens during S-phase. Be able to name the stages of mitosis and know what events take place in each.   Know what sister chromatids are.   Understand the term diploid and haploid, and know what homologous chromosomes are, how they are
similar to each other and how they differ from nonhomologous chromosomes. Know the important events that occur in meiosis and understand how meiosis differs from mitosis. Be able state how many chromosomes and pairs of homologous chromosomes are present in cells of a
given diploid number that are undergoing meiosis. Understand the terms tetrad, chiasmata, crossing over
and recombination.   Skill -- be able to solve genetics problems similar to those in the first homework assignment related to
chapter 2.
Review of Mendel’s Principles and Probability in Genetics (Lectures 2,3, Chapter 3). Be able to state Mendel's postulates (Random Segregation and Independent Assortment) and understand
their significance.   Know and be able to use the terms, phenotype, genotype, homozygous, heterozygous, dominant, recessive,
allele, true breeding (or pure breeding), parental generation, F1 generation, F2 generation, F1 hybrid,
monohybrid cross, dihybrid cross.   Be able to solve simple genetic inheritance problems similar to those in homework assignment 1 related to
chapter 3. Be able to read a genetic family tree for humans (pedigree) and be able to determine from the tree whether
a particular trait is inherited as a dominant or a recessive trait. Be able to solve genetic inheritance probability problems using the product law and the sum law for crosses
resulting in up to three progeny. Understand how Chi Square is used to determine whether genetic data fits predicted theoretical ratios, and
be able to solve probability problems using Chi Square.
