Genetics Flashcards
Chromosomes
46 chromosome / 23 from each parent
Each have Double helix
Genes
Pieces of DNA that have specific instructions
Genes work together with experience to wire our brains
Nucleotides
The structural units of dna and rna
RNA single strand carries the message of DNA to cell body
Genome
Complete set of instructions for making an organism
Consists of all the genetic material and it’s chromosomes
Gene complex
Genes working together to form traits
Traits
Inherited physical characteristic
Can be selected naturally or with the help of man
Passed on
Ex: dog breeds (selective breeding mate selection)
Fox evolution- respond to name
Natural selection
Traits that help an organism survive or adapt to any environment
Fear can be passed on because it helps you survive
Twin studies
Behavior and genetics (nature vs nurture)
How much is behavior impacted by genetics
Genotype
Internally coded, inheritable information
Carried by all living organisms
Phenotypes
Physical characterization
Identical twins
Genetically same
Similar environment
Fraternal twins
Only genetics
Loehlin and Nichols
How parents treat their identical twins
Heritability
Can be inherited
Degree that a trait can be passed on through the genetic code
Prenatal environment
The environment in the womb
Moms diet, etc
