At which stage of mitosis do chromosomes separate at the centromeres? - Answers anaphase
Which protein or protein complex must be degraded for the centromeres to separate? - Answers
Shugoshin
True or false: in prokaryotic cells, the genetic material is stored in the nucleus - Answers False
If a somatic cell of a horse has 32 chromosomes, how many monads are expected to be found
in each gamete? - Answers 16
Assume that a G1 somatic cell nucleus in a female Myrmecia pilosula contains 2 picograms of
DNA. How much DNA
would be found in a single gamete? - Answers 1 picogram
How much nuclear DNA would be found in a somatic cell from a female Myrmecia pilosula
during mitotic prophase?
A. 0.5 picograms - Answers 4 picograms
. True or false: in a healthy male, 40 primary spermatocytes will produce160 spermatozoa. -
Answers True
The figure above shows chromosomes aligned on the equatorial plane during mitosis. For this
particular cell, n = ____. - Answers 4
In which stage of mitosis is the cell above? - Answers metaphase
. How many bivalents would form if a cell like the one above (same genetic content) underwent
meiosis? - Answers 4
In a healthy female, how many ova would be expected to form from 40 primary oocytes? -
Answers 40
True or false: assuming incomplete dominance, a 1:2:1 phenotypic ratio is expected in the F2
generation from a
monohybrid cross - Answers True
Which statement correctly describes a tetrad? - Answers The side-by-side alignment of
homologous chromosomes during meiosis
, True or false: if one gene pair is involved in the pedigree shown above, the mode of inheritance
could be autosomal
dominant. - Answers false
True or false: both female second-generation parents will have the same genotype for the gene
producing the
phenotype above - Answers true
In a genetic experiment, pea plants with round seeds were crossed with pea plants with
wrinkled seeds and the
following offspring were obtained: 21 - Answers Ww x ww
Using the Chi-square test, the p-value for the above data is ___ . - Answers between 0.10 and
0.25
According the Chi-square test, the results of the experiment above ______. - Answers fail to
reject the null hypothesis
True or false: for a single copy gene in humans, only two alleles for that gene will occur in a
single individual - Answers True
True or false: due to its large biomass, the cow is an ideal model organism for genetic studies. -
Answers False
. In the mouse, gene A allows pigmentation to be deposited in the individual coat hairs; its allele,
a, prevents such
deposition of pigment, resulting in an albino. Gene B gives agouti (wild-type black and white
striped fur); its allele b gives
pure black fur (no striping). If a doubly heterozygous agouti mouse mated with a doubly
homozygous recessive white
mouse, what would be the expected phenotypic ratio in the progeny? - Answers 2 albino: 1
agouti: 1 black
Mouse coat color in the question above is controlled by which mode of inheritance? - Answers
Recessive epistasis
In the question above, the agouti parent (the mouse being crossed) has how many total alleles
that relate to mouse coat
color? - Answers 4
A quiescent cell is in which stage of the cell cycle? - Answers G0
