Term
adaptation
Definition
the process or state of changing to fit a new environment or differnet conditions, or the resulting change
Term
allele
Definition
one of two alternative forms of a gene
Term
asexual reproduction
Definition
decribes reproduction in which there is no fusion of male and female sex cells gametes, e.g. vegetative reproduction or budding
Term
behavioral traits
Definition
the way in which a person, organism, or group has learned to respond to a specific set of conditions
Term
behavioral traits
Definition
the way in which a person, organism, or group has learned to respond to a specific set of conditions
Term
budding
Definition
a form of asexual reproduction in which an outgrouth of the parent becomes constricted and eventually separtes to form a new indivial
Term
camouflage
Definition
the devices that animals use to blend into their environment in order to avoid being seen by predators or prey, especially coloration; something that is intened to hide, disguise, or mislead
Term
cellur differentation
Definition
when stem cells begin to specialize into the body cells an organism needs to surive
Term
chromosmoes
Definition
a rod-shaped structure,usaully foundin pairs in a cell nucleus that carries the genes that determine the sex and the characterisitics an organism inherits from its parents
Term
dna
Definition
a molecule in the form of a twisited double strand double helix that is a major component of chromosomes and carries genitic information
Term
dominant
Definition
a gene that causes a parental characterisitic it controls to occur in any offspring
Term
ethical
Definition
consistent with agreed princples of correct moral conduct
Term
fertilization
Definition
the union of male and female reproductive cells to produce a fertilized reproductive cell
Term
fission
Definition
the division of a singled-celed organism into two equal parts, each part growing into a complete organism
Term
genes
Definition
the basic unit capable of trabs mitting characterisitics from one generation to another
Term
genotype
Definition
the letter coding that is assigned to the alleles in genes when tracing family hereditary lines
Term
heredity
Definition
the transfer if gentically controlled characterisitics from of generation to the next in living organism
Term
heredity
Definition
the transfer if gentically controlled characterisitics from of generation to the next in living organism
Term
heterozygous
Definition
describes a cell or organism that has two or more different versions alleles of at least one of its genes
Term
homozygouss
Definition
having two identical genes for each allele in a gene set
Term
hybrid
Definition
an organism that results from the mating fo parent from two distinct species or subspecies
Term
instinctive behavior
Definition
based on a strong natural inpulse
Term
learned behavior
Definition
describes behavior or knowlege that is required through training or experience rather than being instinctual
Term
maiosis
Definition
in organism that reproduce sexually, a process of cell division during which the nucleus divides into four nuclei, each of which contains half the usal number of chromosomes
Term
mimicry
Definition
the resemblance of a plant or animal to another speices ot to a feature of its natural surroudings, developed as protectiopn from other predators
Term
mitosis
Definition
the process by which a cell divides into two daughter cells, each of which has the same number of chromosomes as the original
Term
mutation
Definition
a random change ina gene or chromosome resulting in a new trait or characteistic that can be inherited mutation can be a source of benefical genetic varation, or it can be neutral or harmful in effect
Term
natural selection
Definition
the process where organisms best suited to surivival in their environment achieve greater reproductive sucess, thereby passing advantages genetic characterisitics on to future generations
Term
nucleus
Definition
center of a cell that contains chromosomes and dna
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
offspring
Definition
a persons or an animals young, or sometimes a descendant of a plant
Term
phenotype
Definition
the visible characteristics of an orgaism resulting from the interaction between it's genetic makeup and the enviroment
Term
physical traits
Definition
phenotypes which are determined by genotypes
Term
pollination
Definition
to transfer pollen grains from the male structure of a plant to the female structure of a plant sigma and fertilize it
Term
probility
Definition
the likelihood that an event will occur
Term
purebread
Definition
having abcetors that belong to the same breed or variety as a result of a controllled breeding
Term
punnet square
Definition
visual way of organizing the probility of a certain genetic trit of showing up in successive generations of offspring
Term
reccessive
Definition
used to describe a gene that produces an effect in an organism only when its matching allale is identical
Term
regenation
Definition
to replace lost tissue or lost limb or organ with a new growth, or grow again after loss
Term
runners\offshoots
Definition
a form of asexual reproduction in which offspring develop off of the parent roots or runners coming out of its body
Term
sexual reproduction
Definition
reproduction that involves union of amle and female gametes, each contributing half of the gentic mackup of the resulting zygote
Term
speciation
Definition
tha evolutionary formation of new biological species, usually by one species that divides into two or more species that are gentically unique
