- Phenotype
- the physical apperance or visible traits of an organism
- Genotype
- a genetic make up of allele combinations of an organism
- Homozygous
- an organsim that has two identical alleles for a trait ex)tt TT
- Heterozygous
- an organsim that has two different alleles for a trait ex)Tt
- Codominance
- alleles ar neither dominont or recessive
- Genetics
- scientific study of heredity
- Purebred
- the offspring has the same type of trait of the parent
- Genes
- factors that control traits
- Heredity
- the passing of traits from the parent to the offspring
- Probability
- the likelyhood that a particular event will occur
- Hybrids
- have two different alleles for a trait
- Alleles
- the different forms of a gene
- Dominant Alleles
- the trait that shows in an organism when the allele is present
- Recessive Alleles
- the trait that is hidden when ever the doninant allele is present
- Traits
- physical characteristics
- Know how to write a phenotype and genotpye punnett square

pheno-dominant:reccessive
geno-dominat:hybrid:reccessive - What is the chromosome theory of inheritance
- genes are carried from their parents to their off spring on chromosomes
- What happenes during meiosis
- the chromosomes seperate and are distributed two different cells. The resulting set cells have only half as many chromosome as the other in the organism
