Lots of people get stuck on the clue chromosomal variation determines eye color blood type crossword clue. The answer is almost always the word allele. This short, six-letter word explains why your eyes are blue, brown, green, or gray and why your blood is type A, B, AB, or O.
In this very easy guide, we explain everything step by step. You do not need big science words. We use simple sentences so everyone can understand — even young students, parents helping with homework, and people who just love crosswords.
What Is a Crossword Clue Anyway?
A crossword clue is a short hint that helps you find the right word. The puzzle gives you empty boxes. You fill them with letters that match the clue.
Some clues are funny. Some clues are about sports. Some clues are about science — like this one.
When the clue talks about
- chromosomes
- variation (that means small differences)
- eye color
- blood type
… the answer is usually allele.
The Easy Answer: Allele (6 Letters)
Allele is the word that fits the clue chromosomal variation determines eye color blood type crossword clue best.
Here is why people love this answer:
- It has exactly 6 letters
- It is a real science word
- It explains differences in people
- It appears in many crosswords

What Does “Allele” Really Mean? (Super Simple)
Imagine your body has a big instruction book. That book is your DNA.
The book is split into chapters. Each chapter is a chromosome.
Inside each chapter, there are small recipes. Each recipe is a gene.
Genes tell your body how to make things — like eye color or blood type.
But genes have different versions — just like cookie recipes can be chocolate chip or oatmeal raisin.
These different versions are called alleles.
So:
- One allele → brown eyes (lots of brown color)
- Another allele → blue eyes (very little brown color)
That is why chromosomal variation (small changes on chromosomes) decides your eye color and blood type.
Why Eye Color Is Different for Everyone
Most people have brown eyes. Some have blue. Some have green or hazel.
Here is the simple reason:
- A gene called OCA2 controls the brown color in eyes.
- If you get the “lots of brown” allele from both parents → you have brown eyes.
- If you get the “very little brown” allele from both parents → you have blue eyes.
- Other genes add small touches (green, hazel, gray).
This is why the clue says it determines eye color. The answer is allele.
Why Blood Type Is Different for Everyone
Blood type is easy to understand too.
Doctors talk about four main blood types:
- A
- B
- AB
- O
You get one allele from mom and one from dad.
The three main alleles are:
- A allele
- B allele
- O allele
Here is how they work together:
- A + A = Type A
- B + B = Type B
- A + B = Type AB
- O + O = Type O
- A + O = Type A
- B + O = Type B
Again, the clue determines … blood type points to allele because alleles decide your blood type.

Quick List: Words You Will See in Genetics Puzzles
Here are the most helpful words to remember:
- Chromosome – long piece of DNA
- Gene – recipe inside chromosome
- Allele – different version of a gene
- DNA – the building blocks of life
- Trait – something you can see (eye color, height)
- Blood type – A, B, AB, or O
When a clue asks about any of these, think allele first!
Easy Steps to Solve Any Genetics Crossword Clue
Follow these five steps next time:
- Read the clue slowly.
- Look for words like “eye,” “blood,” “color,” “type,” “variation,” or “chromosome.”

Write allele. It is the number one answer for 6-letter boxes.
What if the puzzle asks for chromosomal variation crossword clue 7 letters or 8 letters?
For 7 letters, try mutants sometimes. For 8 letters, it might be mutation or genetics. But allele is still the most common when eye color or blood type is in the clue.
Is allele the same thing as gene?
No. A gene is like a full recipe in your DNA. An allele is one special way that recipe can be written. You get one allele from mom and one from dad.
Why do puzzles always use eye color and blood type in clues?
These are easy examples everyone knows. Brown eyes or blue eyes, type A or type O blood — all come from different alleles. It makes the clue simple and fun.
