The passing of traits from parents to offspring is known as....

The branch of biology that deals with heredity and differences in organisms determined by DNA.

The genetic information, found in the nucleus of a cell, that serves as the blue prints for everything a cell is and does.

What do we call the specific characteristics of an organism such as hair color, eye color, height, weight, etc?

The shape of DNA is known as a

DNA stands for

Why is DNA important?

DNA is found in the

A segment of DNA that codes for a trait

Sections of DNA that serve as the recipe for a specific trait. Usually represented as stripes or bands on chromosomes.

Genetic traits are determined by one or more

The alleles that an organism has/inherits are its

Long strands of DNA are wrapped into

Structure found inside the nucleus that contains DNA. Each cell contains 23 pairs.

What are the structures in this image called?

The physical expression of a trait.

Brown Hair, blue eyes, and free earlobes are all examples of

Hair color and eye color are examples of a person's....

The observable expression of a trait is its

A version or variation of a gene

What is a genotype?

A person who is homozygous for a trait can have a genotype of....

If a person is heterozygous for a trait, their genotype can be...

If "B" represents brown hair, and "b" represents blond hair, what will the genotype be for a homozygous brown haired person?

If "B" is brown and "b" is blond, what is the phenotype of someone who's genotype is "bb"

How many copies of the recessive gene must there be for that phenotype to show up?

Which set of alleles are considered heterozygous?

The different variations of a gene. Letters are used to represent each version.

For example: B - brown or b - blue

Genotype: TT

Genotype: rr

Genotype: Aa

What is the missing pairing?

Cross 2 heterozygous tall pea plants. Tall (T) is dominant to short (t). What fraction of the offspring do you predict will be tall?

Using the Punnett Square, identify the correct Genotypic ratio

In the problem shown, what must the genotype of the missing parent be?

In humans, freckles (F) on the skin are dominant to no freckles (f).  If a heterozygous parent and a recessive parent conceive, what is the chances of having a child with NO FRECKLES?

In guinea pigs, the allele for rough coat (R) is dominant over the allele for smooth coat (r).  A homozygous dominant guinea pig and a homozygous recessive guinea pig are mated.

What would be the phenotype of the offspring?

Having freckles is a dominant trait in humans.  A girl has freckles, but her brother does not. What do we know for certain about the parents?

In a population of bees, long wings (L) are dominant over short wings (l).  Bees with long wings are ...

Aa, DD, Bb, yy are all examples of _______

Which statement below describes RECESSIVE alleles?

One advantage to sexual reproduction includes

A type of reproduction that involves two parents.

The offspring look different from the parents.

A type of reproduction in which the genetic materials from two different cells combine, producing an offspring

One parent: organism produces offspring without fertilization

A type of reproduction that involves one parent. The offspring look genetically identical to the parent.

In a rare instance when a genetic mutation happens to be helpful to the organism, the new trait would be an example of a(n)

A mistake in DNA replication is known as a

Most Mutations are
