Phenotype
The expression of a specific trait based on genetic and environmental
influences.
Genotype
the genetic makeup of an organism or group of organisms with reference to a
single trait, set of traits, or an entire complex of traits.
Allele
any of several forms of a gene, usually arising through mutation, that are
responsible for hereditary variation.
,Homozygous
having identical pairs of genes for any given pair of hereditary characteristics
Heterozygous
having dissimilar pairs of genes for any hereditary characteristic
Dominant Trait
a trait that will appear in the offspring if one of the parents contributes it
Recessive Trait
a trait that mustt be contributed by both parents in order to appear in the
offspring
Nondisjunction
the failure of chromosomes to separate and segregate into daughter cells at
division
Mutation
a sudden change different than the parent type in one or more heritable
characteristics, caused by a change in a gene or a chromosome
,Genetic Engineering
the development and application of scientific methods, procedures, and
technologies that permit direct manipulation of genetic material in order to
alter the hereditary traits of a cell, organism, or population
Recombinant DNA
DNA in which one or more segments or genes have been inserted, either
naturally or by laboratory manipulation, from a different molecule or from
another part of the same molecule, resulting in a new genetic combination
Transcription
The process by which mRNA is synthesized from a DNA template resulting in
the transfer of genetic information from the DNA molecule to mRNA
Replication
the process by which exact copies of complex molecules, such as DNA
molecules, that occurs during growth of living organisms
Traslation
The process by which mRNA, tRNA, and ribosomes effect the production of a
protein molecule from amino acids, the specificity of synthesis being
controlled by the base sequences of the mRNA
, Ecosystem
the interaction of a community of organisms with their environment
Producer
An autotrophic organism that serves as a source of food for other
organisms in a food chain. Producers include green plants, which
produce food through
photosynthesis, and certain bacteria that are capable of converting inorganic
substances into food through chemosynthesis
Anterior
The front surface of the body
Posterior
Near the tail end of the body
Chemoautotroph
an organism that depends on inorganic chemicals for its energy and
principally on carbon dioxide for its carbon
Dichotomous Key
used to identify a plant or animal in which each stage presents descriptions
of two distinguishing characters, with a direction to another stage in the
key, until the species is identified
