Answer:
50%
Explanation:
According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.
The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.
Answer:
Traits.
Explanation:
Traits in an organism are controlled by the genes. These genes are made up of DNA that is responsible for the unique appearance of the organisms. Some organisms are different from one another because of the DNA that helps the to perform different functions. In the DNA, all information is present about form and structure of the organisms so that's why we can say that traits or characteristics are controlled by genes.
Answer:
independent variable refers to the variable that you change or manipulate in an experiment while the dependent variable is dependent on the independent variable and how you change your independent variable will result in the dependent variables outcome.

For a human offspring to express a paternal mitochondrial gene, the individual must have inherited a mitochondrion from the sperm this is called paternal leakage.
<h3>What is mitochondrial diseases ?</h3>
A disease that develops when cellular energy production systems are broken.
The mitochondria's inability to fully burn nutrients and oxygen to produce energy, which is necessary for healthy cell function, is a common factor across mitochondrial disorders. It's frequently inherited.
Muscle weakness, developmental delays, and poor growth are possible symptoms. Although there is no cure, symptoms can be managed with medicine and physical therapy.
<h3>Causes of mitochondrial myopathies</h3>
Genetic mutations lead to mitochondrial disorders. Proteins are made according to instructions provided by genes, and the genes causing mitochondrial illness typically produce proteins that function inside mitochondria.
