Some examples of somatic gene disorders include cancer (mutations in somatic cells leading to uncontrolled cell growth), cardiovascular diseases (genetic alterations affecting heart function), and neurodegenerative diseases (such as Alzheimer's and Parkinson's, caused by mutations in somatic cells).

What is gene therapy?
Gene therapy is a method used to treat or prevent disease by introducing genetic material into a person’s cells. This can involve replacing a faulty gene, introducing a new gene to help the body fight disease, or using other techniques to modify gene expression. Gene therapy has the potential to treat various genetic disorders and other diseases at their root cause.
What are the dominate alleles?
Dominant allele disorders are single gene disorders which take effect in the heterozygous state.
Which type of disorder is most difficult to correct by gene therapy?
Multifactorial disorders, such as heart disease and diabetes, are the most difficult to correct with gene therapy. These disorders involve a combination of genetic, environmental, and lifestyle factors, making it challenging to target a single gene for treatment. Additionally, the complexity of these disorders increases the risk of unintended consequences from gene therapy.
How many gene is present in one chromosomes?
A given gene is present on exactly two chromosomes in a somatic cell.
What isa genetic disorder?
A genetic disorder is a health condition caused by an abnormality in an individual's DNA. These disorders can be inherited from parents or arise from spontaneous mutations. They can impact various aspects of a person's health and development.
What type of gene does gene therapy try to replace in a sick person?
somatic gene
Why all somatic cells undergo mitosis and some cells in the gonads undergo meiosis?
Somatic cells undergo mitosis for growth, repair, and maintenance of the body, resulting in identical copies of the original cell. Cells in the gonads undergo meiosis to produce gametes with half the number of chromosomes, ensuring genetic diversity in offspring when fertilization occurs. This process also helps maintain the chromosome number across generations.
What disorders can benefit from gene therapy?
Congenital genetic defects, epigenetic defects, and even some forms of cancer triggered by oncogene activation can all be resolved by gene therapy.In addition, acquired disorders, such as herpes or HIV infection, can also be theoretically cured by gene therapy.
What kinds of somatic cell gene mutations can frequently lead to the first stages of cancer?
Proto-oncogene is the kind of somatic cell gene mutation that can lead to first stages of cancer. Proto-oncogene can lead to cellular transformation.

What are the Dominic?
Dominant allele disorders are single gene disorders which take effect in the heterozygous state.
How is gene expression controlled?
name the genetic disorders
Are alleles recessive?
Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
What difference does it make if a mutation occurs in a somatic cell or in a gamete?
If the mutation occurs in a somatic cell and the cell is still able to reproduce, the mutation continues in the daughter cells in following generations. If a mutation occurs in a gamete, the original organism remains unchanged. If that gamete is used for reproduction, then the mutation will continue in the offspring.
What are the dominate alleles?
Dominant allele disorders are single gene disorders which take effect in the heterozygous state.
What are genetic disorders that involve more than one defective gene?
Some examples of genetic disorders involving more than one defective gene are cystic fibrosis, which is caused by mutations in the CFTR gene and other modifier genes; and certain types of neurofibromatosis, which result from mutations in both the NF1 and NF2 genes. These disorders demonstrate the complexity of genetic inheritance and the interactions between multiple genes.
What autosomal disorders in humans are controlled by dominant alleles?
Some autosomal disorders in humans that are controlled by dominant alleles include Huntington's disease, Marfan syndrome, and neurofibromatosis type 1. These disorders are expressed when an individual inherits a single copy of the mutated gene from one parent.
