Explanation:

1. DNA is made of nucleotides. So, "Genetic mutations refer to alterations in the sequence of nucleotides that make up an organism's DNA."
2. Silent mutations don't change the amino - acid due to genetic code redundancy. So, "Silent mutations occur when the altered codon still codes for the same amino acid due to the redundancy of the genetic code."
3. Point mutations change a single nucleotide. So, "Point mutations involve changes in a single nucleotide within the DNA sequence."
4. Frameshift mutations alter the reading frame. So, "Frameshift mutations occur when the insertion or deletion of nucleotides alters the reading frame of the genetic code."
5. Phenotypic changes result from mutations. So, "Phenotypic changes due to mutations can range from physical characteristics to susceptibility to diseases."
6. UV radiation causes mutations in skin cells. So, "Ultraviolet (UV) radiation from the sun is known to cause mutations in skin cells when exposed excessively."
7. DiGeorge syndrome is caused by a chromosome 22 deletion. So, "DiGeorge syndrome is caused by a deletion in a small segment of chromosome 22."
8. Heterozygous sickle - cell anemia carriers have a selective advantage against malaria. So, "In regions where malaria is prevalent, individuals carrying the heterozygous form of sickle cell anemia have a selective advantage against malaria."
9. Mutations contribute to biodiversity within species. So, "Mutations contribute to biodiversity by creating and maintaining genetic differences within species."
