Initiation Before we start, on the table at the top, record on a scale from 1-10 (10 is strong), how do you feel about the things that will be on the test: Vocabulary Mitosis Meisosis Genetics (Punnett Squares) Pedigrees

Directions You are reviewing for tomorrow’s test– this is more than a game, it is a review. – Meaning: take notes (if you don’t know it, look it up!), try not to look at notes while you are reviewing, ask questions Mr. Berning has final say on scoring. You are playing for bragging rights, scientific knowledge and the coveted Gregor Mendel certificate of DOMINATION

Task One 1.What is this process called? 2.How many daughter cells are produced? 3.What kinds of cells are produced (haploid or diploid)? 4.What kinds of cells are produced (body cells or gametes)? 5.What happens in metaphase?

Task Two 1.What is this process called? 2.How many daughter cells are produced? 3.What kinds of cells are produced (haploid or diploid)? 4.What kinds of cells are produced (body cells or gametes)? 5.What is something unique that happens in meiosis I?

Task Three MITOSISMEIOSIS Type of cells produced Number of chromosomes in daughter cells (compared to parent cells) Creates haploid or diploid cells? # of daughter cells per parent cell List phases in order

MITOSISMEIOSIS Type of cells producedBodyEgg/Sperm Number of chromosomes in daughter cells (compared to parent cells) Whole/Complete (e.g. 46) Half (e.g. 23) Creates haploid or diploid cells? DiploidHaploid # of daughter cells per parent cell 24 List phases in order Interphase, Prophase, Metaphase, Anaphase, Telophase Interphase I, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II

Task Four A bone cell of a male dog has 78 chromosomes. How many chromosomes are in the dog’s skin cells? How many chromosomes are in it’s sperm cells?

Task Five Most cells of a cat contain 38 chromosomes. Some of its cells, though, are found to contain 19 chromosomes. – What kind of cells contain 19 chromosomes and by what process are they produced? – What kind of cells contain 38 chromosomes and by what process are they produced?

Task Six: Rapid Fire Vocab Alleles Genotype Phenotype Homozygous Heterozygous Gamete

Vocab Alleles- different forms of a gene Genotype- Genetic (Aa) characteristics of an organism Phenotype- Physcial characteristics of an organism Heterozygous- (hetero = different); Organisms with two unlike alleles for a trait Homozygous- (homo= same); Organisms with two like alleles for a trait Haploid- Cells with half the number of chromosomes Diploid- (di = two) Cells with two sets of chromosomes Gametes- sex cells (egg and sperm)

Task Seven Achondroplasia is the most common form of dwarfism (makes up 70% of dwarfism). Achondroplasia is a dominant, meaning short stature is dominant over tall stature. 1. Using the letter A as the allele for dwarfism: 2. Cross a heterozygous individual with a homozygous recessive. (must show punnett square) 3. Genotype ratio? 4.Phenotype ratio? GenotypePhenotype AA = Aa= aa=

Task Eight What is the genotype of individual 1 in the 1st generation? How do you know? What is the genotype of individual 2 in the 2 nd generation? How do you know?

Task Nine Was Mendel wrong? Given what we know about how blood types, height, blended characteristics, etc., was Mendel wrong? Why or why not? Give an example of the following types of genetics: – Complete dominance: – Incomplete dominance: – Codominance: – Multiple Alleles:

Termination (go back to the table you filled out at the beginning of class) Write down what you know how to do and what you need to study tonight: – Vocabulary – Mitosis – Meiosis – Genetics Problems – Pedigrees Write down how you will study for this test
