Typical single or a few nucleotide changes.
Aneuploidy Correct Answers Variation in the number of
particular chromosomes within a set.
Antigens Correct Answers foreign substances that trigger the
attack of antibodies in the immune response.
Barr body Correct Answers A dense body formed from a
deactivated X chromosome.
Breakpoints Correct Answers The breaks leading to the
inversion occur in a vital gene
calico cats Correct Answers usually on females, yellow and
black alleles on x chromosome - female has 2 X's
Chi-square analysis Correct Answers the examination of
frequencies for two nominal-scaled variables in a cross-
tabulation table to determine whether the variables have a
significant relationship
chromosomal inversion Correct Answers When part of the
chromosome becomes oriented in the reverse of its usual
direction
, chromosomal translocation Correct Answers occurs when part

Codominance Correct Answers A condition in which neither of
two alleles of a gene is dominant or recessive.
Conditional lethal Correct Answers lethal alleles whose
expression is dependent on "environmental conditions"
Copy number variation Correct Answers a type of structural
variation in which a segment of DNA that is 1000 bp or more in
length commonly exhibits copy number differences among
members of the same species.

present at birth and affects both the respiratory and digestive
systems.
cytogeneticist Correct Answers a scientist who studies
chromosomes under the microscope
Deletion Correct Answers A change to a chromosome in which
a fragment of the chromosome is removed.

to resist certain types of diseases (while other varieties of the
same plant are typically susceptible.)
