A small segment of a chromosome that contains the instructions for one specific trait.

Gene

100

The physical appearance or visible characteristics of an organism.

Phenotype

100

A graphic organizer used to predict the possible genotypes and phenotypes of offspring.

Punnett Square

100

A plant has the genotype Tt. If it self-pollinates, what is the probability (percentage) that an offspring will be TT?

25%

100

Where does food start in the digestive system

Mouth

200

A genotype where the two alleles are different (e.g., Tt).

Heterozygous or Hybrid

200

The genetic makeup of an organism, represented by a combination of letters.

Genotype

200

These are placed on the outside (top and left) of the square to represent the parents' contribution.

Alleles 

200

In a cross between BB and bb, what is the only possible genotype for the offspring?

Bb

200

What is it called when water moves from high concentration to low concentration

Osmosis 

300

A genotype where both alleles are the same (e.g., TT or tt).

Homozygous or purebred

300

If a pea plant is "Tall," is that its genotype or its phenotype?

Phenotype

300

In a standard monohybrid cross between two heterozygous parents (Bb x Bb), this is the percentage chance of a recessive phenotype.

25%

You cross two heterozygous "Hybrid" mice (Bb x Bb). Whaat are the possible phenotypes?

B= Long Hair

b= Short Hair

400

The different forms or "versions" of a single gene.

Allele

400

This type of allele is always written with a capital letter.

Dominant

400

You cross two organisms that are heterozygous for two traits (AaBb x AaBb). Out of 16 offspring, how many are expected to show both recessive phenotypes (aabb)?

1

To find the alleles for a dihybrid cross of GgYy, you use the FOIL method. What are the four possible combinations for one parent?

GY, Gy, gY, and gy?

400

What is an organelle that is in a plant cell but not an animal cell

Cell wall or Chloroplast

500

A term often used to describe an organism that is "homozygous" for a specific trait.

Purebred
500

This type of allele is only seen in the phenotype if two copies are present.

Recessive

500

A heterozygous tall plant (Tt) is crossed with a short plant (tt). what percent should be short?

50%

500

In a dihybrid cross of RrYy x RrYy, how many offspring out of 16 will show the Dominant trait for the seed color and the Recessive for pod length trait for the second?

R= Yellow seeds

r= Green Seeds

Y= Long pods

y= Short pods
