Today’s Lesson:

Review Understanding Inheritance

DI: Genotypes

All sexually reproducing organisms have 2 parents

  • Genotypes are written showing 2 alleles

    • (one inherited from each parent)

    • Ex. Bb, TT, tt

  • What symbols should be used?

    • Use the first letter of the dominant phenotype (form)

    • Use the same letter for both dominant and recessive phenotypes

      • Uppercase - dominant

      • Lowercase - recessive

    • Dominant alleles are always written first

  • Write only genotypes to match the phenotypes of the individual.

    • Write two allele symbols for each genotype.

      • Homozygous - both alleles are the same (either dominant or recessive)

      • Heterozygous - one allele is dominant and the other is recessive

  • Dominant phenotypes can be homozygous - RR or heterozygous Rr

    • Either way the dominant allele shows (expresses)

  • Recessive phenotypes are always homozygous - rr

    • Any dominant allele would mask the recessive

Practice - complete the genotype worksheet

To Be Completed:

Today’s Lesson:

Finish Sexual reproduction Notes:

Vocabulary:

Fertilization - joining of egg an sperm

  • (in humans results in 23 pairs of chromosomes)

Zygote - fertilized egg

  • able to grow through mitosis

Meiosis - cell division process that makes sex cells

  • produces haploid cells with random 1/2 of the chromosomes

  • Each sex cell is unique - never duplicates

  • insures all offspring are unique

Diploid - body cells with pairs of chromosomes

Haploid - sex cells with random 1/2 of the chromosomes

Advantages of Sexual reproduction

  • Increased genetic diversity

  • makes diverse organisms

  • differences may be an advantage that increases survival

Quiz Monday - Sexual Reproduction, Meiosis (and Mitosis)

  • Please review your notes.

  • No need to turn them in, but make sure they are complete.

Corpse Flower in GC due Sunday Midnight.

Thursday, March 4, 2021. Day 5

Review “Asexual; and Sexual Reproduction - Amoeba Sisters”

Review BrainPOP Pollination

Sexual reproduction Notes, March 3, 2021

Sexual reproduction

  • two parents contribute genetic material

    • Each gives 1/2 of the DNA

  • create genetically unique offspring

  • used by animals, plants, fungi, and protists

Vocabulary:

Egg - female sex cell (animals)

  • made in ovaries

  • (in humans contains 23 single chromosomes)

  • pollen in plants

Sperm - male sex cell (animals)

  • (in humans contains 23 single chromosomes)

  • made in testis

  • ovule in plants

fertilization - joining of egg an sperm

  • (in humans results in 23 pairs of chromosomes)

Zygote - fertilized egg

  • able to grow through mitosis

Meiosis - cell division process that makes sex cells

  • produces haploid cells with random 1/2 of the chromosomes

Diploid - body cells with pairs of chromosomes

Haploid - sex cells with random 1/2 of the chromosomes

Advantages of Sexual reproduction

  • Increased genetic diversity

  • makes diverse organisms

  • differences may be an advantage that increases survival

Quiz tomorrow?

Tuesday, March 2, 2021. Day 3

Do Now:

To Be Completed:

Assign: Asexual and Sexual reproduction - Amoeba Sisters Worksheet

Today’s Lesson:

I am out tomorrow.

  • You are expected to complete work during class today

    • stay in the meet

  • all work is due tomorrow by midnight

  • You will get an assignment for tomorrow as well.

Lets Go!

Review: Comparing Types of Cell Division: Mitosis and Meiosis

Compete the Mitosis-Meiosis Comparison Chart in GC

Students given 5 minutes

Assign: Asexual and Sexual reproduction - Amoeba Sisters Worksheet

Work on this the remainder of class.

Due Wednesday.

Friday, February 26, 2021. Day 1

Do Now:

To Be Completed:

Today’s Lesson:

Read about sexual reproduction

  • Pages 235 to 237 (Sexual Reproduction) of Chapter 7 Reproduction of Organisms.

Complete the "Sexual Reproduction QnA Wksht

  • use the chapter reading for your source of information - not Google

  • Watch the "Read along" video for help

Complete the "Mapping Sexual Reproduction" google drawing.

Turn it all in!

Breakouts anyone?

Thursday, February 25, 2021. Day 6

Do Now:

To Be Completed:

Amoeba Sisters: Mitosis Video Activity in GC

  • due tomorrow.

Today’s Lesson:

Go over Mitosis Activities.

  • diagram

  • quiz worksheet

Pass back Quiz Results

Last Call - parthenogenesis.

Add to notes: Mitosis

Mitosis

  • Eukaryotes grow by cell division

    • makes more cells - get larger

    • also for repair of damage

  • Mitosis is process for cell division

    • it is asexual reproduction of the cell

      • (not the multicellular organism)

    • 1st DNA is copied into two identical sets

    • Then each set separates and forms two identical nuclei

      • with identical chromosomes

    • Cell divides in two

      • genetically identical daughter cells

Review and go over Activity worksheets in GC

  • In some classes, GC made multiple copies of this assignment.

    • I will be deleting extra copies

  • I will keep the “copy at the top of the stream

    • copy/past your responses to that one

  • All students to go over and correct

    • Turn in if your grade is less than a “4”

Asexual Reproduction - outline notes

Asexual reproduction

  • one parent produces one or more offspring

  • offspring genetically identical to parent

  • occurs via various methods

Forms of Asexual Reproduction

Capture.JPG

Advantages of Asexual Reproduction

  • fast reproduction

  • no need for mate - less time/energy

  • get to pass on all your genes - not half with a mate

Disadvantages

  • low/no genetic diversity

  • all offspring may be susceptible to a change in conditions
