People with achondroplasia can be born to parents who don't have the condition. This is the result of a new mutations. New gene mutations leading to achondroplasia are associated with the paternal age effect (over 35 years old). Studies have demonstrated that new gene mutations for achondroplasia are exclusively inherited from the father and occur during spermatogenesis.

Is achondroplasia dominant or recessive?
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.
In incomplete dominance genotypes can be expected to appear in a ratio of?
The expected phenotype for a Mendal F1 monohybrid cross is 3:1. Looking at heterozygous parents (F1) who share the same dominant trait, e.g. Straight tail.Crossing two heterozygous parents from the F1 generation results in an F2 generation that produces a 75% chance for the appearance of the dominant phenotype, of which two-thirds are heterozygous, and a 25% chance for the appearance of the recessive phenotype, giving the ratio 3;1.Inheritance pattern of dominant and recessive phenotypes when each parent is homozygous for either the dominant or recessive trait. All members of the F1generation are heterozygous and share the same dominant phenotype, while the F2generation exhibits a 3:1 ratio of dominant to recessive phenotypes.
If a Eurasian mother and caucasian father have a child will it look Asian or caucasian From a genetic standpoint?
There is no way to answer that with out knowing the dominate and recessive traits of both the mother and the father and doing some very long punnett squares with the phenotypes for each. Even after doing that, everything is left up to chance. The punnett squares only offer the percentage or odds of a child having ONE particular trait or another so there is no definite answer.
Is achondroplasia hereditary?
yes, achondroplasia is hereditary and if one of a parent has it you have 50% chance to inheriting it.
What type of inheritance is achondroplasia?
Achondroplasia is inherited by the parents as a dominant disease. It occurs from a defect in the FGFR3 gene. It usually occurs spontaneously. if both parents have the disease they have a 25% chance of having a normal sized child, a 50% chance of having a child with Achondroplasia, and a 25% chance of the child getting both genes from each parent which results in death.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.

Is Alzheimer's Disease a genetic disorder?
Yes and no. see if your grand parents had it, there could be a chance that you might develope alzheimer's disease, but you might also develope alzheimer's disease just from old age. So from that, under any circumstances, there is the chance of developing alzheimer's anytime after the 40-50 y/o mark.
Did real and chance get married?
not at all!
When two loci are on the same chromosome the phenotypes of the progeny sometimes do not fit the phenotypes predicted?
The same reason that dice don't always roll numbers as expected. Random chance. genetic propagation of traits is much more complex and therefor even less predictable than dice.
