inheritance

 [in-her´ĭ-tans]
1. the acquisition of characters or qualities by transmission from parent to offspring.
2. that which is transmitted from parent to offspring; see also gene, deoxyribonucleic acid, and heredity.
intermediate inheritance inheritance in which the phenotype of the heterozygote falls between that of the two homozygotes.
maternal inheritance the transmission of characters that are dependent on peculiarities of the egg cytoplasm produced, in turn, by nuclear genes.

in·her·i·tance

(in-her'i-tans),
1. Characters or qualities that are transmitted from parent to offspring by coded cytologic data; that which is inherited.
2. Cultural or legal endowment.

mitochondrial inheritance  the inheritance of traits controlled by genes on the DNA of mitochondria in the ooplasm; thus the genes are inherited entirely from the maternal side, segregate randomly at meiosis or mitosis, and are variably expressed.

inheritance

1. The acquisition of a particular set of genes (GENOME) from the entire series of a person's forebears, by way of an equal number of genes from each parent.
2. The characteristics transmitted in this way.

inheritance

The acquisition of traits, characteristics and disorders from parents to their children by transmission of genetic information. Genes come in pairs: one originating from the father, the other from the mother. If an individual presents only the hereditary characteristics determined by one gene of the pair on an autosomal chromosome, that gene is called dominant. Conditions caused by such genes are said to show autosomal dominant inheritance. For instance, for a rare autosomal dominant disease, if one parent is affected, then on average about 50% of their children will also be affected, irrespective of the children's sex. Examples: Marfan's syndrome, congenital stationary night blindness, neurofibromatosis 1 and 2, von Hippel-Lindau disease. If the individual does not present the hereditary characteristics unless both genes in a pair are of the same type, then the gene is called recessive. Conditions caused by such genes are said to show autosomal recessive inheritance. For a rare autosomal recessive disease, if a child is affected, then on average about 25% of their siblings will also be affected, irrespective of their sex. Examples: Laurence-Moon-Biedl syndrome, Tay-Sachs disease, oculocutaneous albinism, galactokinase deficiency.Thirdly, inheritance may be controlled by genes on one of the sex chromosomes, most often the X chromosome. A recessive mutation on the single X chromosome carried by a male will cause a disease, whereas in the female, a recessive X chromosome mutation would have to be carried on both of her X chromosomes. Therefore in X-linked recessive inheritance (sex-linked recessive inheritance) males are affected more often than females. Examples: colour blindness, ocular albinism, choroideremia. A fourth type of inheritance considered in ophthalmic practice is mitochondrial (maternal) inheritance in which the inheritance of a trait encoded in the mitochondrial DNA is transmitted through the female line (mother to son or mother to daughter). Examples: Leber's hereditary optic atrophy; Kearns-Sayre syndrome. See acquired; chromosome; defective colour vision; gene; hereditary.

2. that which is transmitted from parent to offspring. See also gene, deoxyribonucleic acid and heredity.
Mendelian inheritance is the basis of all genetic practice, but it has limitations in explaining the small differences that occur in a range of offspring of similar and related matings. Galtonian genetics deals specifically with this problem and is better fitted as a tool in population genetics and in dealing with characters that are dependent on a number of chromosomal loci rather than on a single locus.

autosomal inheritance
controlled by genes located on autosomes.
intermediate inheritance
inheritance in which the phenotype of the heterozygote falls between that of either homozygote.
maternal inheritance
the transmission of characters that are dependent on peculiarities of the egg cytoplasm produced, in turn, by nuclear genes.
X-linked inheritance

Patient discussion about inheritance

Q. Is Autism hereditary? My 3 year old son has been diagnosed with autism last year. I am now pregnant with my second child and am scared that he will too have autism.

A. There is a higher chance that your additional children will have autism too, however its not a given. Be more alert and notice any early signs that your child may develop.

Q. Is Leukemia hereditary? My Grandpa died of Leukemia when he was 50. I am worried that it might be hereditary. Is it?

A. Overall leukemia is not hereditary but there are rare reports of family clusters, that is, more than one case in a family. Therefore, you should consult your Doctor and tell him about your family's medical history.

Q. Is migraine hereditary? If both my parents suffer from migraines does it mean I can't avoid it?

A. Yes, migraines do have a very strong genetic correlation. However, it does not mean that if both your parents have it, you will have it too for 100%. It means only that you have a much higher risk than the regular population, that does not have migraines in their family, to suffer from this condition.
