Cells and the Nucleus
- Cells are the smallest unit of life
- Cells are the building blocks of all life
- The nucleus is the "brain" of the cell
- The nucleus holds DNA
1 min
Purpose of Cell Division
- Cells divide to make reproductive cells (sperm and eggs)
- Reproductive cell division produces unique cells, not clones
- New reproductive cells have only one set of chromosomes (half)
- Reproductive cells can combine and share a full set of chromosomes
- Most cell division produces exact clones with full sets of chromosomes
- Cells divide for organism repair
- Cells divide for organism growth

Chromosome and DNA
- DNA is the blueprint for building an organism
- A chromosome is packed with DNA
- Chromosomes exist in pairs
- Humans have 23 chromosome pairs
- Chromosomes are found in the nucleus
1 min
Genes and Alleles
- A gene is a fragment of DNA that codes for a trait (hair color)
- An allele is a form of a gene that codes for a specific characteristic (brown hair)
- Half of a child's genes and alleles come from each parent
1 min
Dominant vs. Recessive
- Dominant allele dominates over recessive allele
- If both alleles are present the dominant phenotype is expressed
- The recessive phenotype is expressed only with two recessive alleles
- Examples of dominant characteristics are widow's peak, dark hair, and dark eyes
- Examples of recessive characteristics are straight hairline, light hair, and light eyes
2 mins
Homozygous vs. Heterozygous
- Description of Genotypes
- Homozygous has 2 of the same allele (AA or aa)
- Homozygous dominant is AA
- Homozygous Recessive is aa
- Heterozygous has 2 different alleles (Aa)
2 mins
Genotype vs. Phenotype
- Genotype is the genetic makeup
- Genotype is coded in DNA
- Genotype is shown as 2 letters that represent 2 alleles
- Genotype is the code for phenotype
- Phenotype is physical appearance of organism
1 min
Heredity
- Passing characteristics from parent to offspring
- Those characteristics can be similar to or different from parents
- Half of the genes come from the father
- Half of the genes come from mother
- Recessive characteristics not expressed in either parent can be expressed in a child
- Some phenotypes are more favorable than others in Natural Selection
2 mins
Hybrid Punnett Square
- Gregor Mendel
- Two Hybrid Parents Mate
- 3 children have the same phenotype
- 1 child has a different phenotype
1 min
Blood Types
- Allele A is Dominant
- Allele B is Dominant
- Allele O is Recessive
- Genotypes AA and AO have Type A Blood
- Genotypes BB and BO have Type B Blood
- Genotype AB is co-dominant and has Type AB Blood
- Genotype OO Results in Type O Blood

- From England
- Naturalist
- Traveled to the galapagos islands
- Developed the theory of Natural Selection
