Genotype
Definition
Genetic makeup of an organism
Term
Sponateous Generation
Definition
Powerful theory (Aristotle); retarded medicine/ microbiology for 2 millenia
Term
Walter Sutton (1902)
Definition
Geneticist proved GENES are located on chromosomes
Term
Homunculus
Definition
Little man in SPERM cell; associated with PREFORMATION theory
Term
Lamark (18th Century)
Definition
Promoted theory of ACQUIRED CHARACTERISTICS (use and disuse)
Term
Charles Darwin
Definition
Environment = NATURAL selector of most adapted phenotypes
Term
Gregor Mendel
Definition
Called "Father of Genetics"; preformed genetic crosses with garden peas
Term
Particulate Inheritance
Definition

Mendel's great contribution; genes inherited as distinct units--unchanged

Term
3:1
Definition
Classic F2 Phenotype ratio from a MONOHYBRID CROSS (Tt x Tt)

1:1
Definition
Phenotype ratio from the cross of a homozygous and heterozygous (Pp x pp)
Term
9:3:3:1
Definition
Classic F2 phenotype ratio from a DIHYBRID cross (no linkage)
Term
August Weismann
Definition
German biologist; disproved Lamarck's theory of Acquired Characteristics
Term
Test Cross
Definition
Pp x pp (Cross determines genotype of a given dominant Phenotype)
Term
Law of Random Assortment
Definition
Occurs at METAPHASE I; Homologous chromosomes align opposite
Term
Pangenes
Definition
Chemicals from each organ blended together at FERTILIZATION
Term
Phenotype
Definition
Physical/physiological VISIBLE result from a given genotype
Term
Dominant Allele
Definition
This allele will be expressed in the PHENOTYPE
Term
Recessive Allele
Definition
Gene variant that is not expressed when associate with dominant Allele
Term
2n
Definition

Formula for calculating # of GAMETE types if you know # of HYBRIDS

Term
