affected by an autosomal dominant disease and a normal parent carries a 50% risk
dominant disease, but the of transmitting the disease gene.
mother does not have the

is a heterozygote, what is
the chance that their first
child will be affected by the
autosomal dominant

muscular dystrophy. He Duchenne muscular dystrophy is an X-linked recessive
inherited this condition disorder. Steven inherited the abnormal X-linked gene
from his: from his mother.
Turner syndrome
Which of the following
The karyotype of an individual with Turner syndrome
aneuploidy disorders is
does not involve the Y chromosome and therefore
found only in females?
cannot occur in males.
, monosomies and trisomies.
Nondisjunction, or failure of a chromosome to separate
during meiosis, results in an ovum with two copies of the
Chromosomal chromosome and an ovum with no copies of the
nondisjunction results in: chromosome. When these ova encounter a male
gamete (sperm), the resulting embryo will have either an
extra copy of the chromosome (trisomy) or one copy of
the chromosome (monosomy).
