genetic variation
differences in the gene
sequences of organisms
within the same species
condensed molecules of dna
inherited from each parent
that contain the same genes
in the same locations but may
contain different alleles
different versions of the same
gene
body cells, such as muscle
cells and neurons
specific sections of dna
molecules that contain
instructions for making
proteins

Explanation:

• genetic variation: Defined as genetic differences between members of the same species.
• homologous chromosomes: Pairs of chromosomes (one from each parent) with matching gene locations, possibly different alleles.
• alleles: These are alternate forms of a single gene.
• somatic cells: Refers to all non-reproductive body cells of an organism.
• genes: Functional DNA segments that code for proteins (or functional RNA).

Answer:

1. genetic variation - Differences in the gene sequences of organisms within the same species
2. homologous chromosomes - Condensed molecules of DNA inherited from each parent that contain the same genes in the same locations but may contain different alleles
3. alleles - Different versions of the same gene
4. somatic cells - Body cells, such as muscle cells and neurons
5. genes - Specific sections of DNA molecules that contain instructions for making proteins
