What is a theory? a comprehensive explanation of how something
works
What are hypotheses? proposed explanations for a given phenomenon
What is the nucleus and it is the center of the cell; it contains chromosomes
what does it contain? and genes
what are chromosomes? threadlike structures composed of DNA molecules
a segment of DNA (spiraled double chain) containing
What is a gene?
the hereditary code
the process by which DNA replicates itself and forms
What is mitosis?
new cells with identical genetic material
the process by which sex cells (gametes: sperm and
What is meiosis?
ova) reproduce
traits we ultimately show influenced by interaction of
what is phenotype?
genotype and experience
what is genotype? the biological influence on all traits
the study of the influence of heredity and
What is behavioral
environment on individual differences in human traits,
genetics?
abilities, and behaviors
, What is meant by range of genes set limits on potential, and environment
reaction? determines how much of that potential is achieved
heredity narrows range of development to only one
What is canalization?
or a few outcomes
What is meant by "gene- many traits are supported by both genes and
environment environment
correlations"?
What is meant by A form of genetic inheritance in which the phenotype
"dominant-recessive reflects only the dominant allele of a heterozygous
inheritance"? pair
In dominant-recessive dominant, always
inheritance, some genes
are______ and are
____________ expressed
regardless of the gene
they are paired with
in dominant-recessive recessive, only, recessive
inheritance, some genes
are_______ and will
___________ be expressed if
paired with another
_____________ gene
What is incomplete A genetic inheritance pattern in which both genes are
dominance in genetics? expressed in the phenotype
What is an example of a blood type (ex. person who is heterozygous with the
characteristic in which one alleles for blood type A and B will express both A and
can see incomplete B alleles and have blood type AB)
dominance at play?
when a trait is a function of the interaction of many
What is polygenic
genes, such as with height, intelligence, and
inheritance?
temperament
