Hemophilia is one.. it's where a person has a mutation in one of the genes responsible for blood clotting. It means the blood doesn't clot and the person could bleed to death.
Down syndrome - is when a person has an excess of Chromosome 21

What most mutated genes are which cause human disorders?
A mutated gene is just a gene that doesn't have the correct DNA or alleles.. Depending of the human disorder the gene that is mutated will be different... We use genes throughout our bodies but ALL genes can cause human disorders but there is NO single gene that, when mutated, creates ALL genetic modification...
Summarize how genetic disorder can result from mutation?
A genetic disorder can result from a mutation by changing a gene's instructions for making a protein. If there is a mutation in one of these genes, this can be passed on from parent to offspring.
How can a small change in a persons DNA cause a genetic disorder?
Some genes encode products that regulate the translation of other genes, or the activity of other proteins, so one small change will affect a lot of other genes/proteins. If that change affects something critical it might lead to a genetic disorder.
What does a mitochondrial genetic bottleneck result in?
The result is considerable variability in the amount of mutated mtDNA molecules that each of the offspring inherits
What are some of the harmful and positive effects of genetic mutations?
Genetic mutation have a few effects to look out for. First of all, a genetically mutated body part or organ will not function as long as an average body part or organ. However, in some cases, these mutations are helpful for those whom could otherwise use them as prosthetic organs or body parts. In addition, people whom have a genetic mutation are sometimes given a monthly check if their mutation prohibits them from every day tasks.

The genetic disorder sickle cell disease is an example of heterozygous dominance?
Yes. Heterozygous dominance offers a way to preserve the mutated allele.
Cystic fibrosis is an example of?
Cystic fibrosis is an example of an autosomal recessive genetic disease. It is caused by the mutation in the cystic fibrosis trans membrane regulator (CFTR) gene. This gene codes for a chloride ion channel important in creating digestive juices, mucus and sweat. A single mutated copy of the CFTR gene does not lead to disease. There have to be mutations in both alleles in order for the disease to manifest. Therefore, it is labeled as an autosomal recessive genetic disorder.
What are two genetic disorder that are caused by a recessive allele on the X chromosome?
well, I am in a sophmore Biology class and learned today the answer to your question. One disorder would be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated x chromosomes. The mother would have to carry the mutated chromosome because the male only has one and in order for the offspring to receive 2 mutated x chromosoms the mother will obviously need to be carrying it as well as the father. Another recessive genetic dissorder you can get is called "Hemophilia." This is a disorder in which the genes for hemoglobin are not present, and your body is not able to create blood clots and a simple scratch can be very serious. It can be treated with injections of clotting protiens. HOPE THIS HELPS

What are two sex-chromosome disorders?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
How is usher syndrome inherited?
Usher syndrome is inherited as an autosomal recessive trait. The term autosomal means that the mutated gene is not located on either of the chromosomes that determine a person's sex; in other words, both males and females can have the disorder and can pass along the disorder to a child. The word recessive means that to have Usher syndrome, an individual must receive a mutated form of the Usher syndrome gene from each parent. If a child has a mutation in one Usher syndrome gene but the other gene is normal, he or she is predicted to have normal vision and hearing. Individuals with a mutation in a gene that can cause an autosomal recessive disorder are called carriers, because they "carry" the gene with a mutation but show no symptoms of the disorder. If both parents are carriers of a mutated gene for Usher syndrome, they will have a one-in-four chance of having a child with Usher syndrome with each birth.
What are genetic diseases caused by?
Genetic diseases are malfunctions in the chromosomes, genes, DNA, cell development or natural hereditary of mutated genes.
Are mutated cells different than good cells?
Yes, "good" cells are just regular, while a mutated cell is exactly that; a cell with a genetic mutation.
Why doe mutated DNA have no effect on future offspring?
Mutated DNA can have an effect on future offspring because DNA is the coding of life a mistake can cause genetic diseases or even death. The genetic code is half paternal and half maternal so if there is any genetic mistake in their DNA can then get passed on through the generations.
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
Summarize how genetic disorder can result from mutation?
A genetic disorder can result from a mutation by changing a gene's instructions for making a protein. If there is a mutation in one of these genes, this can be passed on from parent to offspring.
