Genetics since Mendel
1) produces a phenotype that is intermediate between two homozygous parents.
1) trait that is controlled by more than two allele and may produce more than three
phenotypes of that traits.
1) An organism is a collection of traits, inherited from parents
2) Hereditary - passing of traits from parents to offspring
Genetics: Study of how traits are inherited through interactions of alleles
1) Genes on chromosomes con
1) Any living things is an ORGANISM. It can vary in size from the microscopic bacteria in mud
puddle to anything living.
Living Things are Organized
1) Living thing is made up of cell. Cell is the smallest unit of an organism t
LT = Living things
How are Living Things Classified?
1) Place similar terms together, you classify them Organisms also are classified into groups.
History of Classification
1) More than 2,000 years ago, Aristotle (Greek) observed living t
1) Cell is a smallest unit that is capable of forming life functions.
2) All cells have a cell membrane - all cells have an outer covering
3) Inside every cell is a gelatin-like material - Cytoplasm
In cytoplasm of every cell is hereditary
*Moving Cellular Materials
1) Cells take in food, oxygen and other substances.
- Release waste materials into environments
- Has membrane around cell, like window screen in the room
2) Things move through cell membrane: depends on size o
1) Deoxyriborucleric acid or DNA: genetic material of all organisms; makes up of two
twisted strands of sugar - phosphate molecule + nitrogen bases.
2) Well cell divides, DNA code is copied + passed to new cells.
1) Mid - 1800s - scien
IV. DATA ANALYSIS
1 Find another group that analyzed a different sample than your own, and share your data and
observations from the lab. You should have one sample with only calcium carbonate as the active
ingredient, and one sample with both calcium car
