Question

Explain how the results exclude the possibility that the trait is encoded by a mitochondrial gene.

Answer 1

Results can exclude the possibility of a trait being encoded by a mitochondrial gene by demonstrating patterns of inheritance that do not align with maternal inheritance or non-Mendelian inheritance. These patterns of inheritance can be observed through studies of inheritance patterns and analysis of genetic phenotypes.

Step-by-step explanation:

Results can exclude the possibility that a trait is encoded by a mitochondrial gene by demonstrating patterns of inheritance that do not align with maternal inheritance. For example, if a trait is inherited in a Mendelian pattern, with equal contribution from both parents, it would not be encoded solely by mitochondrial DNA.

Additionally, if the trait displays non-Mendelian inheritance, such as incomplete dominance or codominance, it indicates that it is not solely controlled by mitochondrial genes. Therefore, the results of inheritance pattern studies and analysis of genetic phenotypes can provide evidence to exclude the possibility of mitochondrial gene encoding for a trait.

Answer 2

Mitochondrial gene is the gene which inherited from mother tothe offspring.

Step-by-step explanation:

Some portion of DNA is also present in the mitochondria of the cell so mitochondrial gene is also transmitted from parent to their offspring. In humans, mitochondrial gene is transmitted from only one parent i. e. mother not father. The mitochondrial disease occurs in the human if the disease is present in the mother because it is transferred through genes from mother to their offspring. There are variety of diseases that occurs due to mitochondrial gene such as Mitochondrial myopathy, Diabetes mellitus and deafness etc. So the mitochondrial gene plays a vital role in the structure and function of human body.
