Analysis Of Ichthyosis
Ichthyosis is a rare hereditary skin disease with a worldwide incidence rate is around 4 per thousand. Since skin is the biggest organ of our body, ichthyosis seriously damages the normal sweat and metabolic function of the skin. Therefore the patient's skin appears at different degrees of dry peeling, keratosclerosis hardening, and the skin is covered with brown scale, which is common in human limbs. Those severe patients with thickening dark scale and full of the whole body, which seriously affects not only the normal life but also even the metabolism of kidney and other organs, also do harmful to the health of those severe patients.

∙ 15y agoAchondroplasia is an autosomal dominant condition. This means that an achondroplasic child can be born from one of the three possible ways. The first is if one of the parents has the disorder and the other is a big person. In this case there is a fifty percent chance that the child will be born a little person and a fifty percent chance that it will be born a big person. If both parents are little people they would have also have a fifty percent chance of having an achondroplasic child. However they would only have a twenty five percent chance of having a big person. The other twenty five percent would be born homozygous dominant. These children are said to have homozygous achondroplasia. This condition is almost always lethal in the first year of life and virtually all are spontaneously aborted at birth. The last possible way of having a child with this disorder is when two big people give birth to a little person. Seventy five percent of the little people living today came about due to this process. This process is known as a new mutation and occurs when the sperm is somehow develops into carrying the achondroplasic allele. Once this happens it is just as if one of parents is carrying the gene

What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Is vulcan dominant or recessive?
The Vulcan is the dominant expression.The earthling sign is recessive.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
What can be dominant or recessive?
Alleles can be dominant or recessive
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is a widows peak dominant or recessive?
Dominant definitely not dominant. It is recessive objectively and subjectively and unequivocally.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
How do you xxplain dominant and recessive?
Recessive
