Autosomal Recessive
two copies of an abnormal gene must be present in order for the phenotype to be
expressed
2 copies of the gene mutation for the offspring to inherit
both parents have to have the autosomal recessive gene




X-linked dominant
dominant trait or disorder caused by a mutation in a gene on the X chromosome
phenotype expressed in females and males
most of the time the offspring does not survive




x-linked recessive
mutation in a gene on the X chromosome causes the phenotype to be expressed
in males who inherit the gene as well as females who are homozygous for the
mutation
carrier females do not express phenotype




A mother is a carrier for x-linked recessive Emery-Dreifuss muscular dystrophy
gene. The father has not been tested but does not exhibit the phenotype that
would normally be showing at his age (upper and lower extremity weakness,

like?
a. Non-carriers 50%, Carrier 25%, Affected 25%
