Heredity
This is the passing of traits from parents to offspring.
heredity
Eye color, leaf shape, and hair texture are all examples of this.
traits
This molecule contains all the instructions for how a living thing looks and functions.
DNA
This word describes the combination of genes you inherit from your parents.
genotype
This word describes the observable traits you can actually see, like hair color or dimples.
phenotypes
You get half your genes from each of these two people.
parents
This is why one cat might have long fur while another has short fur.

These are the small sections of DNA that determine specific traits.
genes
These two things—one from your mom and one from your dad—make up your genotype.
copies of each gene
Your phenotype depends on this “hidden” set of instructions inside your genes.
genotypes
This explains why siblings look alike but not exactly the same.
the unique combination of genes they inherit
Traits make each organism this — no two individuals are exactly alike.
unique
DNA is found inside this part of the cell.
nucleus
This type of gene is written with a capital letter and shows up even if a recessive gene is also present.
dominant gene
Rolling your tongue, having freckles, or having curly hair are all examples of this.
phenotypes
Puppies resemble their parents because of this process.
heredity
This type of trait can be observed directly, like color or shape.
physical trait
Humans have between 25,000 and 35,000 of these.
genes
f “B” is dominant and “b” is recessive, this genotype would still show the dominant trait.
Bb
This outside factor can influence your phenotype, even though it’s not part of your DNA.
environment
These structures carry the genes that parents pass to their children.
DNA
These differences in traits help scientists study how organisms vary within a species.

A dog’s fur color, a strawberry’s shape, and a tree’s height are all influenced by these.
genes
This type of gene is written with a lowercase letter.
recessive gene
This is why identical twins might not look exactly the same as they grow up.
