Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.
In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.
Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.
Although a part of your question is missing, you might be referring to this question:
Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?
a. Recessive diseases are unmasked by additional copies.
b. The genes are found in a novel arrangement.
c. Gene dosage is modified.

If you are asking if that is true or false, it is false because all fungus like protists are heterotrophs, not autotrophs
Gene therapy can improve the society by being able to treat a wide range of diseases, such as cancer, heart disease, etc.
<h3>What is Gene therapy?</h3>
A gene is referred to as the the basic physical and functional unit of heredity and is present in the DNA of living organisms. On the other hand gene therapy is the process in which there are changes made to the human genome in other to treat a disease or illness.
This is usually done by introducing a normal gene into an individual's genome in order to repair different types of mutation and has been effectively proven to have such type of property.
Gene therapy generally ensures that different types of sicknesses are successfully treated by the healthcare professionals thereby decreasing the mortality rate.

Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years
