Cards

Term
character
Definition
heritable feature that varies among individuals
ex: flower color
Term
trait
Definition
each variety of the character
ex: white or purple
Term
hybridization
Definition
crossing of two breeding varieties
Term
P generation
Definition
parental generation
Term
F1 generation
Definition
first filial generation. hybrid offspring of P generation
Term
F2 generation
Definition
2nd filial generation. Hybrid offspring of F1 generation
Term
phenotype
Definition
organisms appearance (ex. purple flower)
Term
genotype
Definition
organisms genetic makeup
Term
homozygote
Definition
having identical alleles for a character
ex. PP
Term
heterozygote
Definition
having nonidentical alleles for a character
ex. Pp
Term
particulate hypothesis
Definition
genetic material behaves like a deck of cards that can be
shuffled but the cards remain discrete heritable units = genes (‘Gene’ idea)
Term
blending hypothesis
Definition
genetic material mixes and behaves like a stack of color.
Example: blue and yellow blends to green color.
FALSE
Term
relationship btwn gene & allele
Definition
allele: alternate form of a gene
Term
complete dominance (of an allele)
Definition
one allele is dominant
Term
incomplete dominance (of an allele)
Definition
neither allele is completely dominant
Term
co-dominance
Definition
Two alleles affect the phenotype in separate, distinguishable
ways
Term
pleiotrophy
Definition
one gene influences multiple, seemingly unrelated phenotypic traits
Term
epistasis
Definition
the expression of a gene at one locus changes the expression of a gene on a different locus
(labrador example)
