schedule
Today’s schedule Pick-up daily notes
Complete the warm-up: Mitosis and meiosis are both forms of cell division. Please list and/or describe 1 similarity and 2 differences between them.
*The warm-up will be displayed on the smartboard as students enter.
Discuss the warm-up.
PowerPoint begins at this point:
5-Alive Recap: Lively 5 minute review/recap of previous lesson
*if this goes over 5 min that is fine
Introduce today’s topic and objectives (will be written in hand-out as well as on whiteboard)
BrainPOP video
Vocabulary review
Group assignments (by me, pre-determined)
Classwork page: complete together
Bean-otype lab activity: complete in small groups
Discuss lab as class
Homework will be independent practice on genotypes, phenotypes, & Punnett squares
Exit ticket
Also turn in lab pages upon exiting
common core
MSDE (2012):INDICATOR3.3.2 The student will illustrate and explain how expressed traits
are passed from parent to offspring.
Assessment limits: phenotypes (expression of inherited characteristics) dominant and recessive traits sex-linked traits (X-linked only; recessive phenotypes are more
often expressed in the male) genotypes (represented by heterozygous and homozygous pairs
of alleles) Punnett square (use to predict and/or interpret the results of a
genetic cross; translate genotypes into phenotypes - monohybrid only)
pedigree (use to interpret patterns of inheritance within a family)
warm-Up
Mitosis and meiosis are both forms of cells division.
Please list/describe
1 similarity & 2 differences between them.
cell divisionmitosis and meiosis
5-alive recap
mitosis
Mitosis: Parent cell (n) creates identicaldaughter cells (n)
Mitosis occurs all over
Mitosis creates all types of cells
meiosis
Meiosis: Parent cell (2n) creates unique daughter cells (n)
Meiosis only occurs in gonads
Meiosis only creates sex cells
differences
Meiosis
Daughter cells are _____ to the parent cell and each other

objectives
Objectives By the end of today’s lesson, students will be able to
discuss Mendelian genetics & heredity using scientific vocabulary with 85% accuracy by practicing it in small groups.
By the end of today’s lesson students will be able to explain the relationship between meiosis & heredity with 85% accuracy by viewing a PowerPoint presentation.
By the end of today’s lesson students will understand, with 85% accuracy, that the sorting and recombination of genes that occurs during fertilization leads to genetic variation among offspring by completing a lab activity.

crucial vocabulary
Genotype: The 2 alleles inherited for a particular gene (the code)
Phenotype: Observable traits (outward expression of the genotype)
Allele: One of two or more versions of a gene
Trait: A specific characteristic of an organism which can be determined by genes or the environment, or more commonly by
interactions between them
Gene : The basic physical unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify
traits; found on chromosomes.
a few more terms…
Dominant vs. Recessive: Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be
expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
Heterozygous: An individual inherits different alleles for a particular gene
from each parent.
Homozygous: An individual inherits the same alleles for a particular gene from
both parents.
Inherited trait: One that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not
strictly determined by genes, but rather are influenced by both genes and environment
Punnett square: A diagram used to determine possible phenotypes.
Pedigree: A genetic representation of a family tree that diagrams the
inheritance of a trait or disease though several generations

Today’s activity!
To observe and understand the genetic variation among offspring we will complete an activity to simulate the sorting and recombination of genes that occurs during fertilization.http://betterlesson.com/unit/1114/070-genetics?from=profile#/document/9018/offspringratios
Students will work in groups assigned by me.
supplies
Supplies for each group
2 bags of beans Please have 1 group member pick up beans from lab
supply table in back of room
Lab sheets (found in your handout package)
Pen or Pencil
bean-otypes
The beans represent the gene for fur color in rats.
Black=B
Black is dominant
Red=b
Red is recessive
methods
Methods:
To be completed collaboratively
Work in small groups
Discuss results as a class
See the lab activity “Offspring, offspring, everywhere” for complete directions (in handout package)
results
Results
Each member of the group will fill in their own results table and write the answers to the results questions.
We will discuss results as a class
Labs will be turned in at the end of class
if you finish early…
If your group finishes the bean-otype lab early, please review the vocabulary list and quietly discuss the terms with your group members.
