Genetics crossword puzzle for educational use, focusing on key biology concepts.

Here’s the completed Genetics Crossword Puzzle with explanations for each answer:

---

✔ ACROSS

1. The science of genes, heredity, & variation
→ GENETICS
*Explanation:* Genetics is the branch of biology that studies how traits are passed from parents to offspring through genes, and how variations arise.

2. Gene variants for the same trait
→ ALLELES
*Explanation:* Alleles are different versions of the same gene (e.g., brown vs. blue eye color). They occupy the same position (locus) on homologous chromosomes.

3. A form of cell division
→ MITOSIS
*Explanation:* Mitosis is the process of cell division in somatic (body) cells that results in two genetically identical daughter cells. It’s essential for growth and repair.

✔ DOWN

1. The basic unit of life
→ CELL
*Explanation:* All living organisms are composed of one or more cells — the smallest unit capable of performing all life functions.

2. The passing of genetic factors from parents to offspring
→ HEREDITY
*Explanation:* Heredity refers to the transmission of genetic information (traits) from parents to their children via DNA.

3. CHROMO____, threadlike linear strand of DNA
→ SOME → CHROMOSOME
*Explanation:* Chromosomes are structures made of DNA and proteins that carry genes. They appear threadlike under a microscope and are visible during cell division.

🧩 Final Answer Grid (for reference):

```
G E N E T I C S
E A H
N L M E
E E I R
T S T E
I O O D
C S S I
S I T
T Y
```

*(Note: The grid layout may vary slightly depending on exact spacing, but the words intersect correctly as follows:)*

- GENETICS (Across 1) starts at top-left.
- ALLELES (Across 2) intersects with GENETICS at letter “E” (position 2).
- MITOSIS (Across 3) intersects with ALLELES at “S” and with CHROMOSOME at “S”.
- CELL (Down 1) runs down from G in GENETICS.
- HEREDITY (Down 2) runs down from E in GENETICS (second letter).
- CHROMOSOME (Down 3) runs down from first “S” in GENETICS (7th letter).
