Friday 2-26-16
Learning objectives:
• How meiosis works
• How sexual reproduction leads to genetic variation
Entry Task:
• If an organism’s haploid chromosome number is 43, which will
the diploid number of chromosomes be?
Diploid and haploid
• Almost all human cells are diploid or containing two
homologous sets of chromosomes
2n = 46
• Eggs and sperm cells (gametes) are haploid or
containing a single set of chromosomes
n = 23

Plan of the day
• Meiosis POGIL
haploid egg and sperm
diploid zygote
In the human life cycle a haploid egg and sperm fuse and form a diploid zygote. Mitosis
produces an embryo with numerous cells that continue to multiply and develop.
Monday 2-29-16
Learning objectives:
• Using Punnett squares to predict outcomes of genetic crosses
Entry Task:
• Explain the process of the crossing over of DNA in
chromosomes, and when it occurs
Plan of the day
• Finish Meiosis POGIL
• Introduce Punnett squares
Phenotype refers to the
observable trait (purple flowers)
Genotype refers to the
combination of alleles (Pp)
• Phenotypic ratio: ratio of
plants with purple flowers to
those with white flowers (3
purple : 1 white)
• Genotypic ratio: ratio of
possible combinations of alleles
(1 PP : 2 Pp : 1 pp)
Probability and Punnett Squares
Probability: Chance of
Something happening
Punnett Square: Diagram
used to show the probability
of a genetic cross
TUESDAY 3-1-16
LEARNING OBJECTIVE:
• MAKE A PUNNETT SQUARE TO PREDICT OUTCOMES OF GENETIC
CROSSES
ENTRY TASK:
haploid egg and sperm
diploid zygote
In the human life cycle a haploid egg and sperm fuse and form a diploid zygote. Mitosis
produces an embryo with numerous cells that continue to multiply and develop.
PLAN OF THE DAY
• WRAP-UP MEIOSIS POGIL
• PUPPY TRAITS ACTIVITY
WEDNESDAY 3-2-16
LEARNING OBJECTIVE:
DIHYBRID CROSSES AND INDEPENDENT ASSORTMENT
ENTRY TASK:

PUNNETT SQUARES – BIKINI BOTTOM GENETICS
DIHYBRID CROSS
crossing of organisms
differing in two characters
Principle of Independent Assortment
During gamete formation in an F2
cross, a particular allele for one
character can be paired with either
allele of another character

WOULD SEGREGATE IN SEX CELLS FROM THIS GENOTYPE FOR
TWO TRAITS?

GENETICS - QUIZ 1
IN PEA PLANTS, ROUND SEEDS IS DOMINANT TO WRINKLED
SEEDS. A HETEROZYGOUS ROUND SEED PLANT IS CROSSED
WITH A HOMOZYGOUS ROUND SEED PLANT. WHAT
PERCENTAGE OF THE OFFSPRING WILL BE HOMOZYGOUS
DOMINANT? ____________
• CREATE A PUNNETT SQUARE BELOW TO SUPPORT YOUR
ANSWER.
Not all traits are inherited
following the patterns found by
Mendel in pea plants
Intermediate or incomplete
inheritance
Multiple alleles – codominance
Polygenic inheritance
Environment - epigenetics
Intermediate or incomplete inheritance
The heterozygotes have a
phenotype that is intermediate
between the phenotypes of the
two homozygotes
Multiple alleles - codominance
For many genes several alleles exist in the
population.
Multiple alleles control the character of blood type
in humans.
There are six possible genotypes.
The alleles IA and IB exhibit codominance,
meaning that a heterozygote expresses both traits.

Polygenic inheritance
 When two or more genes affect a single
character
 In humans, height and skin color have
polygenic inheritance
HOMEWORK DUE TOMORROW FRIDAY

HANDOUT 11.3 QUESTIONS
• AND BIKINI BOTTOM GENETICS HANDOUT IF NOT
FINISHED DURING CLASS
THURSDAY 3-4-16
LEARNING OBJECTIVE:
HOW DOES THE ENVIRONMENT AFFECT GENE EXPRESSION?
ENTRY TASK:
• DO A PUNNETT SQUARE TO SHOW THE RESULT OF CROSSING
A HOMOZYGOUS DOMINANT PUPPY AND A HETEROZYGOUS
PUPPY FOR HAIR COLOR. REMEMBER BROWN (B) IS DOMINANT
OVER YELLOW.
The Environment - Epigenetics
Phenotype depends on
environment as well as genes
Temperature affects fur color in
Siamese cats
In humans
Nutrition affects built
Exposure to sun affects skin
tone
Prenatal exposure to certain
conditions affects offspring’s
mental and physical health
