Science: Genetics And Evolution, organisms Flashcards
_ discovered rules of genetics
He used _ to show how traits are passed
Gregor Mendel
Pea plants
Chart shows all possible genetic combinations
Punnett square
3 copies of chromosome twenty one (error in meiosis)
Down syndrome
_ genetic mutation
One nucleotide is exchanged with another
Ex: AC instead of AT
Substitution
_ genetic mutation
Extra nucleotide pairs are inserted into DNA
Insertion
_ genetic mutation
Removal of nucleotide pairs
Deletion
_ genetic mutation
Insertion or deletion cause gene to be misread
Frameshift
Populations divided by geographic features into two isolated populations
Allopatric speciation
Small sub populations form and become genetically isolated from main population
Peripatric speciation
Two species partially isolated by geography develop characteristics that make them reproductively incompatible
Parapatric speciation
Development of two species from a single population occupying one geographical location
*behavorial, mechanical, temporal isolation
Sympatric
