|
Is recessive allele on the X chromosome expresed in males? |
Yes always |
|
|
Autosomal recessive |
Skip generations Number of affected males is equal to number of affected females |
|
|
Autosomal dominant |
Does not skip generations Number of affected males is equal to number of affected females Affected parent can pass to all or half of offspring |
|
|
Y linked |
Skip generations Affected father has affected sons |
|
|
X linked recessive |
Skip generations Affected female has all affected sons but females vary |
|
|
X linked dominant |
Does not skip generations Affected fathers have all affected daughters Affected mothers can pass the trait equally to sons and daughters |
