Which of the following diseases, syndromes, or conditions is NOT correctly matched to
the genotype or genetic abnormality in humans? See Section 21.1 (Page 226) .
View Available Hint(s)
Cri-du-chat syndrome : deletion of a small segment
of one copy of chromosome 5
Down syndrome : Trisomy of chromosome 21
Turner syndrome : XO for the sex chromosomes
Klinefelter syndrome : XYY for the sex chromosomes - answerKlinefelter syndrome :
XYY for the sex chromosomes
*Explanation
Correct. Klinefelter syndrome is characterized by XXY for the sex chromosomes,
having an extra "X" chromosome. Jacob's syndrome, XYY, is a rare chromosomal
disorder that affects males. It is caused by the presence of an extra Y chromosome.
Males normally have one X and one Y chromosome.
The chance of each of two independent events happening are ________ to determine
the probability that both events would happen together.
added together
multiplied by each
multiplied by twos
squared
divided by two - answermultiplied by each
A testing outcome in which a disease is detected, but the sample/patient in reality does
not have the disease is called a ________.
false negative
true positive
false positive
a standard error
