ABO blood group, alpha-1 antitrypsin deficiency. From this cross, we are able to get the percentages reported in the question. Extra copies cause genes to be expressed at proportionately higher levels, thereby upsetting the balance of gene products. Copyright holder you represent if other than yourself.

Conditions resulting from mutations in mitochondrial DNA can appear in every autosomal recessive sex linked inheritance in Tennessee of a family and can affect both males and females, but fathers do not pass these disorders to their daughters or sons.
Haemophilia A Haemophilia B X-linked sideroblastic anemia. Therefore, sex-linked inheritance is also referred to as X-linked inheritance. Both types of inheritance exist as two types: recessive and dominant.
Which of the following statements about X-linked traits is true? Pedigrees with autosomal dominant traits will show affected males and females arising with equal frequency from a single affected parent. What is horizontal gene transfer and how might it occur?
X-linked recessive disorders are also caused by mutations in genes on the X chromosome.
Because the males are viable, a deletion can be ruled out. Females are capable of carrying a recessive X-linked trait without expressing it, while males are not. An affected woman usually heterozygous for a rare dominant trait will pass on the trait equally to half her daughters and half her sons.
Aneuploidy: loss or gain of one or more chromosomes.
