Chromosome Inheritance (Cornell style notes / SNB page 46-48)

1. Remember: An organism’s traits come from pairs of genes and different forms of a gene are called alleles.
Sutton observed that:
2. The body cells of grasshoppers had 24 chromosomes, but their sex cells only had half as many chromosomes (12 chromosomes).
3. When a sperm and egg joined during fertilization, the grasshopper egg that formed had 24 chromosomes. 12 + 12 = 24
4. Grasshopper offspring have the same number of chromosomes as their parents because half of them come from each parent during sexual reproduction.
5. From Mendel’s work, Sutton knew that one allele in a pair comes from the female parent and the other allele comes from the male parent.
6. Sutton realized that paired alleles were carried on paired chromosomes.
7. Chromosome theory of inheritance:
– genes are carried from parents to their offspring on chromosomes
– one chromosome in each pair comes from each parent
8. Meiosis is the process that reduces the chromosome number by half to form sex cells.
9. During meiosis, the chromosome pairs separate and are distributed to two different cells reducing their number by half.
10. Sexual reproduction produces offspring that inherit half their genes/chromosomes from each parent; making them genetically different from either parent.
11. Chromosomes are made up of many genes joined together like beads on a string.
12. Plant and animal cells contain many thousands of gene pairs on many chromosome pairs.

Genes and Alleles (Cornell Style use SNB pages 41 & 42)

1. DNA is a long, thin molecule that looks like a twisted ladder with rungs made of base pairs. GC and AT (GCAT)
2. Chromosomes are pieces of DNA in the nuclei of each cell. Humans have 23 pair.
3. Genes are a sequence of bases in a chromosome that code for a trait.
(There are an average of 65 million bases per chromosome and an average of 1000 genes per chromosome.)
4. Chromosome pairs – one comes from each parent to make up the pair.
5. Sexual reproduction results in offspring that are genetically different from their parents.
6. Asexual reproduction results in offspring that are genetically the same as their parents.
7. Alleles are different forms of a gene.
8. Organisms get one allele from each of their parents.
9. An organism's alleles can be the same or different.
10. In purebreds, alleles are the same.
11. In hybrids, alleles are different and the dominant allele is responsible for the trait.
10. Punnett Squares are used to determine the probability of alleles in offspring.
11. Dominant Alleles – capital letters / Recessive Alleles – lower case letters
12. See textbook page 164 for how to draw a Punnett Square.

Part 2
Mendel's Work (Use SNB pages 37 & 38. Write as Cornell notes)
1. Heredity is the passing of physical characteristics from parents to offspring.
2. Traits are physical characteristics that can be passed from parents to offspring.
3. Genetics is the study of heredity.
4. Mendel is considered the father of genetics.
5. A new organism begins to form when male and female sex cells join in the process called fertilization.
6. A purebred organism is the offspring of many generations that have the same trait.
7. Mendel’s Experiment:P Generation – In the Parent Generation, a tall purebred was cross with a short purebred.Mendel’s Experiment:
8. 1st Generation – All of the offspring were tall. None of the offspring were short even though one parent was short.Mendel’s Experiment:
9. 2nd Generation – Offspring occurred in the ratio of three tall plants to one short plant.
10. The short trait of one parent of the parent generation did not occur in the 1st generation, but reappeared in the 2nd generation.
11. The factors that determine traits are called genes.
12. P Generation:One parent had two tall genes.The other parent had two short genes.
13. F1 Generation:All offspring have one tall and one short gene.
14. F2 Generation: Three possibilities:Can get a tall gene from both parents.Can get a tall from one parent and a short form the other.Can get a short gene from each parent.
15 Summary:
  • Traits are controlled by two genes.
  • One gene comes from the female parent and the other comes from the male parent.
  • One gene of a pair can hide or dominate the trait of another gene.
  • Offspring receiving two hidden or recessive gene will have the hidden trait

Cell Cycle
Part 1
(use SNB pages 24 to 28 /Cornell style with no summary)
Cell Cycle
1.All multicellular organisms start out as one cell.
2.Organisms get bigger by producing more cells through the process of cell division.
3.The regular sequence of growth and division that cells undergo is called the cell cycle.
4.Interphase, mitosis, and cytokinesis are the three stages of the cell cycle.

Part 2
Interphase / Cell Cycle Stage 1
1.A cell grows to its mature size and spends most of its time functioning normally during interphase.
2.Interphase is considered the “living phase” of the cell cycle.
3.Late in interphase a cell will make a copy of its DNA; called replication.
4.Finally in interphase a cell will produce structures that it will use to divide.

Part 3
Do this, look and learn! Don’t copy.
Look at the X shaped structures called chromosomes on page 131 of your textbook.
DNA and special proteins in the nucleus forms these X shaped structures when the nucleus divides.
The material (DNA and proteins) found in the nucleus and chromosomes are called chromatin.
Half of each X is called a chromatid.

Part 4
Mitosis /Cell Cycle Stage 2
1.One nucleus divides into two nuclei during mitosis.
2.Duplicate copies of the DNA are separated into two new nuclei.
3.Prophase, metaphase, anaphase, and telophase are the four phases of mitosis. (P,MAT 4 your puppy)
4.DNA forms chromosomes during prophase.
5.The chromosomes line up across the center of the cell during metaphase.
6.Centromeres split and chromatids separate during anaphase.
7.A new nuclear envelope forms around each region of chromosomes in telophase.

Cytokinesis / Cell Cycle Stage 3
1. During cytokinesis, the cytoplasm divides and organelles are distributed into each of the two new cells.
Each daughter cell has the same number of chromosomes as the original parent cell.

Part 5
Anwer the four questions on page 134.
Then draw and label the picture.

Part 6
Draw and label the Cell Cycle on textbook pages 132 & 133.
Draw only the green cells on SNB page 27 or 28.
Chromatids look like “V”or “^”/ chromosomes “X”
Use these as explanations for each number.

1. Interphase: The cell grows to its mature size, makes a copy of its DNA, and prepares to divide into two cells.
2a. Mitosis- Prophase: DNA forms chromosomes.
2b. Mitosis- Metaphase: the chromosomes line up across the center of the cell.
2c. Mitosis-Anaphase: centromeres split and chromatids separate.
2d. Mitosis-Telophase: new nuclear envelopes form around each region of chromosomes.
3. Cytokinesis: The cell membrane pinches in around the middle of the cell. The cell splits in two. Each daughter cell ends up with an identical set of chromosomes and about half of the organelles.
