One of the parents of a cross has a mutation in its mitochondria. In ...
Mitochondria are organelles found in cells that are responsible for producing energy in the form of ATP. They have their own DNA, known as mitochondrial DNA (mtDNA), which is separate from the nuclear DNA found in the cell's nucleus.

In this question, one of the parents of a cross has a mutation in its mitochondria. This means that the mutation is present in the mtDNA of that parent. The question states that this parent is taken as a male, indicating that it is the male parent in the cross.

During the segregation of the F2 progenies, the mtDNA is inherited exclusively from the mother. This is because the mitochondria are primarily passed down from the mother to the offspring through the cytoplasm of the egg cell. The sperm cell, on the other hand, contributes only nuclear DNA to the offspring.

Given that the parent with the mtDNA mutation is the male parent, the offspring will not inherit the mutated mtDNA. Therefore, the mutation will not be present in any of the progenies (F2 generation).

To summarize:
- The mitochondria are primarily inherited from the mother.
- The parent with the mtDNA mutation is the male parent.
- The mutation will not be present in any of the progenies (F2 generation).

Hence, the correct answer is option B: none of the progenies.

Mutation is a sudden alteration of the chemical structure of a gene or the alteration of its position on the chromosome by breaking and re-joining of the chromosome. It has occurred in male parent. But organelles like mitochondria, chloroplast etc. are a part of cytoplasmic inheritance.
Cytoplasmic inheritance is the passage of traits from parents to offspring through structures present inside the cytoplasm of contributing gametes. Plasma genes occur in plastids, mitochondria, plasmids and some special particles like kappa particles, sigma particles, etc. In higher organisms cytoplasmic inheritance is called maternal inheritance because the zygote receives most of its cytoplasm from the ovum. Therefore, cytoplasmic inheritance is usually unparental. So none of the progeny will show mutation.
