Mitochondrial DNA is passed from mother to daughter because during fertilization, the sperm typically donates very little, if any, mitochondria to the zygote. This results in the mitochondrial DNA being inherited solely from the mother. It is the egg that contributes the majority of the mitochondria to the embryo.

Why are mitochondrial diseases exclusively inherited from the mother?
Mitochondrial diseases are exclusively inherited from the mother because mitochondria, the energy-producing structures in cells, are passed down from the mother's egg cell to the offspring. Sperm cells do not contribute mitochondria to the embryo, so any genetic mutations in the mitochondria will only be inherited from the mother.
Can a mother give a sex-linked trait to her son and her daughter?
The short answer is yes! The allele responsible for a sex-linked trait is carried on the X chromosome which a mother passes on to both sons and daughters. However, since sons have only that one X chromosome (from the mother - the other is the Y from the father) then even a recessive trait will always show up in the son. It is unlikely to show up in the daughter since the daughter inherits a second X chromosome from the father and since most traits are recessive then the 'normal' allele on the paternal X chromosome will mask the recessive one inherited from the mother. This is why the vast majority of people in the population showing a sex-linked trait are males. However, if the daughter were to inherit the recesisive allele from the father (as well as the mother) then she would be homozygous and the trait would show up....
How are daughter cells different from the parent cell in binary fission?
Daughter cells are genetically identical to the parent cell because binary fission is a form of asexual reproduction where the parent cell divides into two identical daughter cells. The only difference between daughter cells and the parent cell is that they are smaller in size.
Are male genes passed down?
Apparently yes they are.You can look at it in the chromosomal level.Genes from both male and female are passed down to the child.A good example is the sex chromosome.Male gives X or Y and the female gives only X.
Does replication provide a means for passing DNA from cell to cell and organism to organism?
Yes, replication is the process by which a cell makes an identical copy of its DNA to pass on to daughter cells during cellular division. Through replication, cells can pass genetic information to offspring or future generations.
What relation is Paula to her mother's mother's only daughter?
If Paula's mother's mother had only one daughter, that is the same as saying that Paula's grandmother had only one daughter. Therefore Paula is the daughter of the only one daughter that her grandmother had.
Your mother died and left her daughter a joint account can anyone draw money out of that account?
No. As with any bank account only the account owner can withdraw money from the account. If the mother set up the account as a joint account with her daughter (with both mother's and daughter's name on the account as joint owners) the full ownership of the account passed to the daughter when the mother died. No one else can make withdrawals.

This scenario is possible if the two mothers are a grandmother, her daughter, and her granddaughter.
