Dominant Factor and Recessive Factor - Principles of Inheritance and Variation - Class 12 All the above-mentioned traits are controlled by genes present on the 22 pairs of autosomes non-sex chromosomes.Copyright WWW. Joubert syndrome Many develop seizures, sometimes refractory, and some may have nonspecific dysmorphic features. Developmental delays. Our son has an Occult submucus cleft palate, he has the 22Q11 or "DiGeorge" syndrome. It can also be on genetic and caused by the child's environment in the womb and in very few cases the child's tongue blocks the palate from fully closing. Which condition is an example of dominant recessive inheritance?
One of the most important principles that governs life is inheritance of genes.
They code for specific proteins that are responsible for various physical features. These features are what makes us look the way we kiss his chest. Such features include our height, skin color, eye color, hair texture, etc. However, they do not just govern our outer appearance but other features like resistance to certain diseases, intolerance to certain chemicals, etc. These include one copy of the gene from the mother and one copy from the father. These two or more variations or forms of genes are called alleles. The interaction between these alleles determines the expression of a gene.
Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. However, recessive traits are those that are expressed only when two copies of an allele are present in the gene. Let us understand this by a simple example.
List of Dominant and Recessive Human Traits
It can be deduced from zre following table:. This can be deduced from the following table:. These are those traits that are governed by a single gene, having two alleles. Therefore, it will result in any of the two forms, with no intermediate results. These are also called the Mendelian inheritance as they follow source inheritance pattern as observed by Mendel in his inheritance experiments. Some of these traits are listed below:. Other factors like co-dominance and incomplete dominance also affect the expression of certain traits. Co-dominance is the phenomenon wherein both are broad lips dominant or recessive disease dominant and recessive are broad lips dominant or recessive disease expresses themselves in the same individual.
A classic example of such an occurrence is the human blood group. Incomplete Dominance is the phenomenon which is exhibited when check this out dominant and recessive alleles blend to give a particular phenotype. The result is always an intermediate between the two alleles. An example of incomplete dominance in humans is that of wavy hair. A cross between straight hair genes homogeneous, SS and curly hair genes homogeneous, ss will result in wavy hair heterogeneous, Ss. Note that in case of straight hair heterogeneous genes, Ss, the result will vary. As the name suggests, these are those features whose expressions are controlled by more than one gene. Since multiple genes are responsible for a kr character, there will visit web page more than two variations of the character.
All the above-mentioned traits are controlled by genes present on the 22 pairs of autosomes non-sex chromosomes. However, there are many genes present on the sex chromosomes X and Y that control link characteristics in humans. The number of genes on X chromosomes are more than the Y chromosomes. Hence, X linked traits are more common. This phenomenon can be categorized as follows:. Human females have two X chromosomes. Hence, a recessive allele coding for a particular trait present on the X chromosome of the mother will be inherited by the son provided the same X chromosome is inherited. This is because the male child has only one copy of X chromosome that comes from the mother and cannot mask its effect. Some examples of this phenomenon are:. X-linked Dominant Traits These traits will make a female child carrier of the dominant allele present on the X chromosome inherited from the father.
Acral manifestations include syndactyly of lkps, broad thumbs or halluces or preaxial polydactyly. The affected rexessive have no intellectual deficit. The condition seems to be hereditary, and transmitted as an autosomal recessive trait. A recessive syndrome characterized by craniosynostosis, mental retardation, seizures, choroidal coloboma, beoad kidneys, bat ears, cleft lip and palate, and beaked nose. Alagille syndrome ALGS is a multisystem disorder with a wide spectrum of clinical variability; this variability is seen even among individuals from the same family.
The major clinical manifestations of ALGS are bile duct paucity on liver biopsy, cholestasis, congenital cardiac defects primarily involving the pulmonary arteriesbutterfly vertebrae, ophthalmologic abnormalities most commonly posterior embryotoxonand characteristic facial features. Renal abnormalities, growth failure, developmental delays, splenomegaly, and vascular abnormalities may also occur. Distinctive facial features are common. Cardiovascular disease includes dilation of the ascending aorta. Some individuals with nonsyndromic holoprosencephaly have a distinctive pattern of facial features, including a narrowing of the head at the temples, outside corners of the eyes that point upward upslanting palpebral fissureslarge ears, a short nose with upturned nostrils, and a broad and deep space between the nose and mouth philtrum.
In general, the severity of facial features is directly related to the severity of the brain abnormalities. However, individuals with mildly affected facial features can have severe brain abnormalities.
Some people do not have apparent structural brain this web page but have some of the facial features associated with this condition. These individuals are considered to have a form of the disorder known as microform holoprosencephaly and are typically identified after the birth of a severely affected family member. Affected individuals also frequently have a malfunctioning pituitary gland, which is a gland located at the base of the brain that produces several hormones. Because pituitary dysfunction leads to the partial or complete absence of these hormones, it can cause https://www.azhear.com/tag/when-my-love-blooms/he-kiss-me-on-my-forehead.php variety are broad lips dominant or recessive disease disorders. Most commonly, people with nonsyndromic holoprosencephaly and pituitary dysfunction develop diabetes insipidus, a condition that disrupts the balance between fluid intake and urine excretion.
Dysfunction in other parts of the brain can cause seizures, feeding difficulties, and problems regulating body temperature, heart rate, and breathing.
The sense of smell may be diminished hyposmia or completely absent anosmia if the part of the brain that processes smells is underdeveloped or missing. Other features may include an opening in the are broad lips dominant or recessive disease of the mouth cleft palate with or without a split in the upper lip cleft lipone central front tooth instead of two a domonant maxillary central incisorand a flat nasal bridge. The eyeballs may be abnormally small microphthalmia or absent anophthalmia. From most to least severe, the types are known as alobar, semi-lobar, lobar, and middle interhemispheric variant MIHV. In the most severe forms of nonsyndromic holoprosencephaly, the brain does not divide at all. These affected individuals have one central eye cyclopia and a tubular nasal structure proboscis located above the eye. Most babies with severe nonsyndromic holoprosencephaly die before birth or soon after.
In the less severe forms, the brain is partially divided and the eyes are usually set close together hypotelorism. The life expectancy of these affected individuals varies depending on the severity of symptoms. Normally, the brain divides into two halves hemispheres during early development. Holoprosencephaly occurs when the brain fails to divide properly into the right and left hemispheres. This condition is called nonsyndromic to distinguish it from other types of holoprosencephaly caused by genetic syndromes, chromosome abnormalities, or substances that cause birth defects teratogens. The severity of nonsyndromic holoprosencephaly varies ddominant among affected individuals, even within the same family. Psychomotor developmental delay is noted in all individuals from an early age.
