12. 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?

13. 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

14. 2 diploid daughter cells
MEIOSIS
MITOSIS
Original diploid cell 2n 2n 2n
2 diploid daughter cells

15. Plan of the day
Meiosis POGIL

17. 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.

18. 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

19. Plan of the day
Finish Meiosis POGIL
Introduce Punnett squares

20. Phenotype refers to the observable trait (purple flowers)
Genotype refers to the combination of alleles (Pp)

21. 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)

22. Probability and Punnett Squares
Punnett Square: Diagram
used to show the probability
of a genetic cross
Probability: Chance of
Something happening

24. Tuesday 3-1-16 Learning objective:
make a Punnett square to predict outcomes of genetic crosses
Entry Task:

26. 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.

27. Plan of the day

29. Plan of the day Dihybrid crosses
Puppy traits activity – Draw, color, and name your dog – Tape it on the outside wall by the door
More practice with genetics vocabulary and Punnett squares – bikini bottom genetics

30. crossing of organisms differing in two characters
DIHYBRID CROSS
crossing of organisms differing in two characters

33. 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

S s O O

35. Plan of the day
Non-mendelian inheritance patterns

36. 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.

37. Intermediate or incomplete inheritance Multiple alleles – codominance
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

38. Intermediate or incomplete inheritance
The heterozygotes have a phenotype that is intermediate between the phenotypes of the two homozygotes

39. 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.

43. Polygenic inheritance
When two or more genes affect a single character
In humans, height and skin color have polygenic inheritance

44. Homework due tomorrow Friday
Read section section 11.3 ( ) and do handout 11.3 questions
And Bikini bottom genetics handout if not finished during class

45. 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.

46. 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
