Science can only explain logical questions and provide answers to things that only can be scientifically proven. Things that are asked in society like religion can not be further explained. The reason why we have religion is because we have always believed in something in history. Either is was made up or concocted out of no where, humans have always believed in something. But what science can't explain is the miracles and things that have happened. Like Jesus, they can't prove that he performed miracles or was the Son of God. They can't prove he and his body ascended into heaven. Science can't explain that God is real. Yet the only thing you can do is believe in it, and trust the Bible accounts are accurately true.
Answer:
Eukaryotes are found in plants, animals, fungi, and protists
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.
