The condition when
chromosomes do not
separate during
Anaphase I or Anaphase II
of meiosis
What is Non-Disjunction?
Condition in which an
individual carries an extra
copy (i.e., three copies) of a
particular chromosome
What is Trisomy?
It is when a fragment of one
chromosome attaches to a
non-homogolous
chromosome (i.e., a different
chromosome that is not part
of the homogolous pair)
What is Translocation?
It occurs when part of a
chromosome is repeated
What is Duplication?
The meiosis phase during
which most mutations to the
chromosome structure occur
What is Prophase 1
…during Crossing Over?
Condition XHXh
heterozygous dominant
for X-link inheritance
What is
female carrier?
In recessive X-link, a father
cannot affect these offspring
What is his sons?
The number of male X
chromosomes
What is one?
Percentage of affected sons
from a heterozygous
dominant mother cross with
an unaffected father in a Xlink dominant disorder
What is 50%?
Percentage of affected
daughters from an
unaffected mother cross
with an affected father in a
X-link recessive disorder
What is zero?
Both daughters will be
carriers. They are
heterozygous (HRHr),
and as such,
carriers of the disorder
A diagram that illustrates the
genetic relationships among
a group of individuals
What is a Pedigree?
The two possible alleles of a
simple dominant trait
What are
Dominant and Recessive?
Circles represent this group
What are Women?
It involves crossing an
individual of unknown
genotype with a
homozygous recessive
individual
What is
a Test Cross?
Chromosomes are directly
involved in determining the
sex of an individual
What is Autosome?
Neither allele for a gene
completely conceals the
presence of the other gene.
What is
Incomplete Dominance?
The allele for a trait is present
on Chromosomes #1-22
What is
Autosomal Inheritance?
Traits do not skip
generations, there is male-tomale transmissions, female
and male offspring are
equally likely to have the trait
What is
Autosomal Dominant
Inheritance?
This process produces a
mixed offspring (i.e., Both
alleles for a trait are equally
and fully expressed).
What is Co-dominace?
The observable
physical and
physiological
characteristics of an
individual.
What is a Phenotype?
DNA structure
What is
a double helix strand?
The backbone of
the double helix strand
What is a sugar group?
Units of inherited information
that carry a code for a
specific trait or function
What is a gene?
It consists of
one sugar group,
one phosphate group
and
one nitrogenous base
What is a nucleotide?
A long chain of
nucleotide subunits
strung together
What is DNA?
