TRAIT – ________________________________________________________________
 ______________ is an example of a ___________ trait.
 ______________ is an example of a ___________ trait.
 ______________ is NOT a trait, even though it can be used to describe someone.

specific people.

ASEXUAL REPRODUCTION – the process that organisms can use to produce ____________
___________________________
 _______________ is technically a form of asexual reproduction; ______________
______________________________.
MUTATION – _____________ changes that can occur during reproduction that produces an
offspring cell that is ________________ from a parent cell
 This can also be true of _____________ organisms; the ___________ organism is
slightly different than the _____________ organism.

GENERATION – the offspring of the same parent or parents regarded as one step or degree
in descent.
 For example: If your grandparents are the top of your family tree, they are
considered the ______ generation. Their ________ are in that generation too.
The __________ of your grandparents (your parents and all their siblings) are the
_________ generation. Their cousins (the children of your grandparents’ siblings)
are part of this generation too. What generation does that make you, your
siblings, and your cousins?? _________________________

ALLELE – any of the possible forms in which a gene for a specific trait can occur
 Alleles for hair color include red, blonde, brown, black, etc.
 What are some alleles for eye color? ____________________________________
DOMINANT – the form of a gene that expresses a trait. The dominant form suppresses the
counterpart form located on the other of a pair of chromosomes.
RECESSIVE – the form a gene that is not expressed as a trait in an individual unless two
such genes are inherited, one from each parent.

HETEROZYGOUS – __________________________________________________________
 My husband’s mom has blue eyes while his dad has brown eyes. Even though my
husband has brown eyes, he likely has both alleles for eye color. His genes contain
the information for BOTH eye colors.
HOMOZYGOUS – ____________________________________________________________
 My parents both have blue eyes. I have blue eyes. It is likely that my genes contain
the information for only blue eyes.

PEDIGREE – a family tree used for ______________
 Pedigrees give us information about the genetic history of a family that we can
use to determine how certain traits are expressed (i.e. dominant or recessive)
CO-DOMINANCE – the traits caused by each allele are both expressed when both are
present
 Roan horses (a color) are neither white nor red, but come from parents that have
those two alleles. A Roan horse is both white and red.
INCOMPLETE DOMINANCE – two alleles are partially expressed often producing an average
(intermediary) of the two
 Purebred red flowers can be crossbred with purebred white flowers to produce
pink flowers. The pink flowers are the “in-between” of red and white.
CARRIER – an individual possessing an unexpressed, recessive gene or the bearer of a
mutation
 My husband is technically a carrier of a “blue eyed” allele. (see ACT. 61)

linked together in a structure resembling a ladder twisted in a spiral called a DOUBLE
HELIX.
 Cytosine
 Guanine
 Adenine

DNA FINGERPRINTING – the use of a sample of DNA to determine the ________ of a
person within a certain probability.
