EXAM 1 (3.1, 6, 8) Flashcards
DNA is packaged into
chromosomes
our entire compliment of DNA is called the
genome
locations on chromosomes that code for proteins are called
genes
specific genetic sequence at a gene location is an
allele
(but note gene and allele are often used interchangeably)
our ______ is responsible for the proteins we produce
DNA
_____ is the term we use for all of our genetic material
genome
(excluding mtDNA found in the mitochondria)
______ are genes that show specific sequence variation from person to person
alleles
(think hair
everyone has the gene for hair, but some people have different variations (ie color, texture, length, this is what makes an allele and allele)
DNA (a persons specific genotype), is the basis of all measurable characteristics, also called
phenotype
the set of observable characteristics of an individual from the interaction of its genotype with the environment
phenotype
genes code for ______, and those ______ influence our traits
proteins
our individual genome is the basis for our individual ________
phenotype
change in inherited characteristics found on a population over time
evolution
alleles (form of a gene) represented in a population change across generations
evolution
______ is a change in gene/allele frequencies over time
evolution
natural selection
the force that leads to the evolution of adaptive traits
adaptive traits
a trait that contains some benefit to the individual with that trait/success of a particular environment
filtration of genes occurs through time because some alleles - due to effects they have on the bodies they inhabit - replicate themselves better than others
the process of natural selection
adaptations arise through natural selection true or false
true
change which results because a specific allele is better able to replicate itself relative to others
adaptive trait
(ex: organism is better able to escape predators, find food, and ultimately, reproduce = that allele is going to be more represented in the next generation)
what’s needed for evolution by natural selection?
- variation in traits exists
-this variation is heritable - there is differential success (survival/reproduction) based on these traits
________ evolution is based on differential survival and reproduction
adaptive
some traits are vestigial, in other words
useless
a trait that has evolved to be functionless (like a belly button) is a _______ trait
vestigial
_______ _______ selects the best existing alternative that is sufficient to “solve the problem”, it doesn’t not create solutions, and is reactive, not proactive
natural selection
define memory
- all information in the mind
- the capacity to store and retrieve that information
- means by which learning occurs
3 forms of memory
- sensory memory
- short term (or working) memory
- long term memory
where does maintenance rehearsal happen
working memory (short term)
where is attention needed in the modal model of the mind
attention is needed from sensory to short term working memory
information stays in the working memory through a process of
maintenance rehearsal
where is information encoded in the mind via the modal model of the mind
information is encoded from short term (or working) memory into long term memory if it has been paid attention to in the sensory memory
where does retrieval happen
from long term into working memory and then is encoded back into long term memory,
note this is where misinformation of past events can occur, changing little details every time you recall and event
echoic memory is
is accessing the last few words of speech and repeating them back as “proof” of their listening
