Genetics Exam 2 Seibenhener Questions With Complete
Solutions
Additions or subtractions of single chromosomes to the
karyotype of an organism produce a greater impact on
phenotype than whole genome changes in ploidy Correct
Answers Why are ANEUPLOIDS more abnormal than
EUPLOIDS?
allelic interaction Correct Answers how alleles interact to form
phenotype
Allopolyploids Correct Answers Hybrids of two different
species with more than one chromosome set
Allosomes Correct Answers determine sex of an individual
organism
Aneuploides Correct Answers are caused by non‐disjunction
during either Mitosis or Meiosis
(Euplodies, Aneuplodies, Monosomies,Trisomies)
Aneuploids // euploids Correct Answers .....are more
deleterious than.....due to changes in gene balance
Aneuploidy Correct Answers changes in PARTS of
chromosome sets
Aneuploidy Correct Answers Chromosome number differs
from a normal individual by PART of a chromosome set
, Aneuploidy Correct Answers Shape and proportions are
generally altered in very specific ways
aneuploidy autosomes Correct Answers lethal in utero
Autopolyploids Correct Answers Having more than one set of
chromosomes originating within a species
autosomal traits Correct Answers Sex linked traits are
generally... and appear only in one sex
Autosomes Correct Answers non-sex chromosomes
chromosomal rearrangements Correct Answers Any type of
chromosomal abnormality involved some change in the structure
of the native chromosome
Chromosome Theory of Inheritance Correct Answers correctly
explains the underlying mechanism of Mendelian genetics by
combining chromosomes with the paired factor postulated by
Mendel.
crossing over Correct Answers exchange of genetic
information between non‐sister chromatids
Differential regions Correct Answers contain specific genes
that have no counter parts on the other Sex Chromosome
diploid (2n) Correct Answers two copies of each chromosome
set
