Denning [Date] [Course title]
, Mitosis and Meiosis II - Correct Ans: In which nuclear division process do sister chromatids segregate?
chiasmata - Correct Ans: At metaphase I, homologous chromosomes are connected only at what
structure?
Pairing of homologous chromosomes - Correct Ans: Which of the following is unique to prophase I of
meiosis?
16 - Correct Ans: 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 - Correct Ans: Meiosis produces ___________ daughter cells
All offspring with red eyes - Correct Ans: 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 - Correct Ans: In a cross between a white-eyed female fruit fly and a
red-eyed male fruit fly, what is the expected outcome?
50% - Correct Ans: 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 - Correct Ans: What
would a female genotype have to be for her to have the genetic disease hemophilia?
p=0.5. All daughters will be affected. - Correct Ans: 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 - Correct Ans: If black and white true breeding mice are mated and the result is
all grey offspring, what inheritance pattern would this be indicative of?
