Question

by dragging and dropping the descriptions at the bottom into the column on the right, match the terms listed on the left with their best description. assume no crossing over events.
homologous chromosome pair
non - homologous chromosome pair
sister chromatid pair
typically has a different set of genes typically has identical alleles typically has the same set of genes, but likely has different alleles

Explanation:

To solve this, we analyze each term:

Step 1: Homologous chromosome pair

Homologous chromosomes are from each parent (maternal and paternal), so they carry the same genes (loci) but may have different alleles (variants) of those genes. Thus, match with "Typically has the same set of genes, but likely has different alleles".

Step 2: Non - homologous chromosome pair

Non - homologous chromosomes belong to different chromosome pairs and carry different sets of genes. So, match with "Typically has a different set of genes".

Step 3: Sister chromatid pair

Sister chromatids are formed by DNA replication of a single chromosome, so they are identical (same alleles) until crossing - over (but the problem states no crossing - over). Thus, match with "Typically has identical alleles".

Answer:

• Homologous chromosome pair: Typically has the same set of genes, but likely has different alleles
• Non - homologous chromosome pair: Typically has a different set of genes
• Sister chromatid pair: Typically has identical alleles
