Which type of Mendelian inherited condition results in both
genders being affected equally in a vertical pattern?
a) Automosomal dominant inheritance
An individual who has an autosomal dominant inherited condition
carries a gene mutation for that condition on one chromosome of a
pair.
b) Automosomal recessive inheritance
The pattern of inheritance in autosomal recessive inherited conditions
is different from that of autosomal dominant inherited conditions in
that it is more horizontal than vertical, with relatives of a single
generation tending to have the condition.
c) X-linked inheritance
X-linked conditions may be inherited in families in recessive or
dominant patterns. In both, the gene mutation is located on the Xchromosome. All males inherit an X chromosome from their mother
with no counterpart; hence, all males express the gene mutation.
d) Multifactorial genetic inheritance
Neural tube defects, such as spina bifida and anencephaly, are
examples of multifactorial genetic conditions. The majority of neural
tube defects are caused by both genetic and environmental influences
that combine during early embryonic development leading to
incomplete closure of the neural tube.
