ASU BIO 340 EXAM 1 COMPLETE STUDY GUIDE
WITH SOLVED QUESTIONS
◉ chiasmata.
Answer: At metaphase I, homologous chromosomes are connected
only at what structure?
◉ Pairing of homologous chromosomes.
Answer: Which of the following is unique to prophase I of meiosis?
◉ 16.
Answer: If a muscle cell of a typical organism has 32 chromosome,
how many chromosomes will be in a gamete of that same organism?
◉ four haploid.
Answer: Meiosis produces ___________ daughter cells
◉ All offspring with red eyes.
Answer: In a cross between a homozygous red-eyed female fruit fly
and a white-eyed male fruit fly, what is the expected outcome?
◉ All male offspring with white eyes.
,Answer: In a cross between a white-eyed female fruit fly and a red-
eyed male fruit fly, what is the expected outcome?
◉ 50%.
Answer: Hemophilia is an x-linked recessive pattern. A carrier
woman (one affected X chromosome) married a man with
hemophilia and they have children. What percent of their boy
children will be affected?
◉ Both of her X chromosomes would have to have the recessive gene
for hemophilia.
Answer: What would a female genotype have to be for her to have
the genetic disease hemophilia?
◉ p=0.5. All daughters will be affected..
Answer: Congenital generalized hypertrichosis is a an X-linked
dominant disease. If an affected male marries an unaffected female,
what is the probability of passing the hypertrichosis gene to his
offspring?
◉ incomplete dominance.
Answer: If black and white true breeding mice are mated and the
result is all grey offspring, what inheritance pattern would this be
indicative of?
, ◉ multiple alleles and codominance.
Answer: ABO blood groups are an example of
◉ Yes, if each parent carries one i allele.
Answer: Could an individual with blood type O (genotype ii) be a
ligitimate child of parents in which one parent has type A and the
other has type B blood?
◉ Incomplete dominance.
Answer: A white splashed (Bl/Bl) Andalausian chicken and a black
(bl/bl) Andalusian chicken are crossed. The heterozygotes produced
show an intermediate phenotype (blue). What inheritance pattern
would this be indicative of?
◉ Codominance.
Answer: A person with only one Sickle Cell Anemia allele and one
unaffected allele will have some normal red blood cells and some
abnormal. What inheritance pattern would this be indicative of?
◉ DNA.
Answer: In Griffith's experiments, what made the harmless R cells
grow capsules when exposed to heat-killed S cells?
