homozygous - CORRECT ANSWERS term used to refer to an organism that has two
identical alleles for a particular trait
heterozygous - CORRECT ANSWERS an organism that has two different alleles for a
trait
phenotype - CORRECT ANSWERS The physical traits that appear in an individual as a
result of its gentic make up.
genotype - CORRECT ANSWERS the genetic makeup, or set of alleles, of an organism
testcross - CORRECT ANSWERS the crossing of an individual of unknown genotype with
a homozygous recessive individual to determine the unknown genotype
monohybrid - CORRECT ANSWERS genetic cross that involves one trait
monohybrid cross - CORRECT ANSWERS mating of two organisms that differ in only
one character
dihybrid - CORRECT ANSWERS Crosses between individuals that differ in two traits
dihybrid cross - CORRECT ANSWERS A cross in which two characteristics are tracked.
law of independent assortment - CORRECT ANSWERS each pair of alleles segregates
independently of each other pair of alleles during gamete formation

multiplication rule - CORRECT ANSWERS to determine the probability, we multiply the
probability of one event by the probability of another
addition rule - CORRECT ANSWERS A rule of probability stating that the probability of
any one of two or more mutually exclusive events occurring can be determined by adding their
individual probabilities.
complete dominance - CORRECT ANSWERS A type of inheritance in which the
phenotypes of the heterozygote and dominant homozygote are indistinguishable.
incomplete dominance - CORRECT ANSWERS production of a phenotype that is
intermediate between the two homozygous parents
codominance - CORRECT ANSWERS A phenotypic situation in which the two alleles
affect the phenotype in separate, distinguishable ways
Tay-Sacks disease - CORRECT ANSWERS A human genetic disease caused by a recessive
allele for a dysfunctional enzyme, leading to accumulation of certain lipids in the brain.
Seizures, blindness, and degeneration of motor and mental performance usually become
manifest a few months after birth, followed by death within a few years.
polydactyly - CORRECT ANSWERS pertaining to having more than the normal number
of fingers and toes
pleiotropy - CORRECT ANSWERS A single gene having multiple effects on an individuals
phenotype (more than one phenotypic expression)
epistasis - CORRECT ANSWERS A gene at one locus alters the phenotypic expression of
a gene at a second locus
