How can mutations or alterations in the mtDNA be inherited?
GaleEncyofNeuroDis
Mitochondria are able to replicate by themselves. When mitochondria replicate, a copy of the mitochondrial DNA is present in the daughter mitochondria as well. This is how they are passed on. Edit: Mitochondrial DNA is passed on maternally (ie the mito. that replicate in a new organism are derived from the mother/egg).

∙ 13y agoMitochondrial DNA is inherited almost entirely from the maternal sex cell (the egg). Therefore, mutations or alterations in the mtDNA can be transmitted from a maternal sex cell to all the mother's children

What do mutations cause in genotype and phenotype?
They cause changes or more technically alterations.
Somatic mutations occur in sex chromosomes and can be inherited?
true
When do the symptoms of mitochondrial myopathies caused by nDNA mutations usually develop?
Generally, nDNA mutations result in clinical symptoms that develop during early childhood, while mtDNA mutations (either directly or as secondary effects from a nDNA mutation) lead to clinical manifestations that develop in late childhood
What DNA mutations are directly linked to inherited diseases?
the ones that have to do with the stuff that is involved such as sexual defencicies
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
What percentage of cancers are estimated to result from mutations that are not inherited?
70% of cancers are estimated to result from mutations that are not inherited.
How are mutations are inherited?
If a mutation occurs in a sex cell, then it may be inherited. Any mutation to the somatic cells will not be passed on. Any mutations that either of the parent organisms have will be inherited by their offspring.

What two process can led to inherited variation in population?
Mutations and emergent properties.

What are the causes of thalassemia?
All types of thalassemias are recessively inherited, meaning that a genetic change must be inherited from both the mother and the father. The severity of the disease is influenced by the exact thalassemia mutations inherited, as well as.
How was the identification of nDNA mutations that cause mitochondrial myopathies first made?
first made when a nuclear gene involved in mtDNA replication was found to be defective in a disorder involving a patient with a mitochondrial myopathy
Can somatic mutations occur in sex chromosomes?
No, they occur in the organism's body cells and cannot be inherited by the offspring .
An inherited disease or disorder that is caused by a mutation in a gene or by a chromosomal defect?
There are many thousands of different mutations.
