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).

Are inherited differences called biological mutations?
Inherited differences are generally not referred to as biological mutations. Mutations are spontaneous changes in DNA that may result in differences in genetic information. Inherited differences, on the other hand, are variations in genetic information that are passed down from parents to offspring.
Somatic mutations occur in sex chromosomes and can be inherited?
true
What cell mutation can be inherited?
Mutations in the germ cells (sperm or egg cells) can be inherited. These mutations can be passed down from parents to their offspring through their genetic material.
What DNA mutations are directly linked to inherited diseases?
Some common DNA mutations directly linked to inherited diseases include the CFTR gene mutation in cystic fibrosis, the BRCA gene mutations in breast and ovarian cancers, and the HTT gene mutation in Huntington's disease. These mutations can be inherited from one or both parents and increase the likelihood of developing the associated disease.
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.
Why can mtDNA be used to see how closely related we are?
Mitochondrial DNA (mtDNA) is inherited maternally and remains relatively unchanged over generations, making it a valuable tool for tracing lineage and evolutionary relationships. Because mtDNA accumulates mutations at a consistent rate, scientists can compare these genetic variations among individuals or populations to estimate their relatedness and divergence. This allows researchers to construct phylogenetic trees and understand ancestral connections across species and human populations. Additionally, the lack of recombination in mtDNA simplifies the analysis of genetic relationships.
Why do inherited traits change over time?
Inherited traits can change over time due to genetic mutations, which are alterations in the DNA sequence that can be passed down to future generations. Changes in the environment or selective pressures can also influence the way certain traits are inherited and expressed. Over many generations, these factors can result in variations in inherited traits within a population.
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 is mtDNA?
MT chromosome, or Mitochondrial chromosomes, are found in the mitochondria of the cell. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA.
What DNA mutations are directly linked to inherited diseases?
Some common DNA mutations directly linked to inherited diseases include the CFTR gene mutation in cystic fibrosis, the BRCA gene mutations in breast and ovarian cancers, and the HTT gene mutation in Huntington's disease. These mutations can be inherited from one or both parents and increase the likelihood of developing the associated disease.
How are inherited mutations different from acquired mutations in terms of their impact on an individual's genetic makeup?
Inherited mutations are passed down from parents and are present in an individual's genetic makeup from birth, potentially affecting their health and traits. Acquired mutations, on the other hand, develop during a person's lifetime due to factors like environmental exposures or lifestyle choices, and may not be passed on to future generations.
When are mutations passed on to future generations?
Mutations can be passed on to future generations when they occur in the DNA of germ cells (sperm and egg cells) that are involved in reproduction. These mutations can be inherited by offspring and become a part of their genetic makeup.
What is a misspelled gene?
A misspelled gene refers to a gene that has mutations or alterations in its DNA sequence, which can lead to incorrect protein production or function. These changes can be due to various factors such as point mutations, insertions, or deletions. Such alterations can result in genetic disorders or contribute to disease susceptibility, as the altered protein may not perform its intended biological role effectively.
