DIALYSIS TUBING BAG:
Which of the following best describes the conditions expected after 24 hours? -

DIALYSIS TUBING BAG:
If, instead of the bag, a potato slice were placed in the beaker of distilled water,
which of the following would be true of the potato slice? - ANSWER: It would gain
mass
'A' represents the dominant allele and 'a' represents the recessive allele of a pair. If,
in 1000 offspring, 500 are 'aa' and 500 are some other genotype, which of the
following are most probably the genotypes of their parents? - ANSWER: 'Aa' and 'aa'
, A form of vitamin D-resistant rickets, know as hypophosphatemia, is inherited as an
X-linked DOMINANT trait. If a male with hypophosphatemia marries a normal
female, which of the following predictions concerning their potential progeny would
be true? - ANSWER: All of their daughters would inherit the disease
Which of the following best describes the parents in a testcross? - ANSWER: One
individual has the dominant phenotype and the other has the recessive phenotype
Which of the following is the most likely explanation for a high rate of crossing over
between 2 genes? - ANSWER: The 2 genes are far apart on the same chromosome
In peas the trait for tall plants is dominant (T) and the trait for recessive plants is
recessive (t). The trait for yellow seed color is dominant (Y) and the trait for green
seed color is recessive (y). A cross between 2 plants results in 296 tall yellow plants
and 104 tall green plants. Which of the following are most likely to be the genotypes
of the parents? - ANSWER: TtYy x TTYy
In humans, red-green color blindness is a sex-linked recessive trait. If a man and a
woman produce a color blind son, which of the following MUST be true? - ANSWER:
The mother carries the allele for color blindness
PEDIGREE (heredity q. 7)
In the pedigree below, squares represent males and circles represent females.
Individuals who express a particular trait are represented by shaded figures. Which
of the following patterns of inheritance best explains the transmission of the trait? -
ANSWER: Autosomal dominant
MOTHER: Type B blood
CHILD: Type A blood
The father must have which of the following blood types? - ANSWER: AB or A
MOTHER: Type B blood
CHILD: Type A blood
If the father has blood type AB, which of the following statements is correct about
the mother? - ANSWER: She contributes an i allele, which is recessive to the father's
IA allele
A male fruit fly with red eyes and long wings was mated with a female with purple
eyes and vestigial wings. All of the offspring in the F1 generation had red eyes and
long wings. These F1 flies were test crossed with purple eyed, vestigial winged flied.
Their offspring, the F2 generation, appeared as indicated below.
125 red eyes, long wings
124 purple eyes, vestigial wings
18 purple eyes, long wings
16 red eyes, vestigial wings
