A small segment of a chromosome that contains the instructions for one specific trait.
Gene
The physical appearance or visible characteristics of an organism.
Phenotype
A graphic organizer used to predict the possible genotypes and phenotypes of offspring.
Punnett Square
A plant has the genotype Tt. If it self-pollinates, what is the probability (percentage) that an offspring will be TT?
25%
Where does food start in the digestive system
Mouth
A genotype where the two alleles are different (e.g., Tt).
Heterozygous or Hybrid
The genetic makeup of an organism, represented by a combination of letters.
Genotype
These are placed on the outside (top and left) of the square to represent the parents' contribution.
Alleles
In a cross between BB and bb, what is the only possible genotype for the offspring?
Bb
What is it called when water moves from high concentration to low concentration
Osmosis
A genotype where both alleles are the same (e.g., TT or tt).
Homozygous or purebred
If a pea plant is "Tall," is that its genotype or its phenotype?
Phenotype
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
Long hair and Short hair

Sabrina Carpenter
The different forms or "versions" of a single gene.
Allele
This type of allele is always written with a capital letter.
Dominant
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?
What is an organelle that is in a plant cell but not an animal cell
Cell wall or Chloroplast
A term often used to describe an organism that is "homozygous" for a specific trait.
This type of allele is only seen in the phenotype if two copies are present.
Recessive
A heterozygous tall plant (Tt) is crossed with a short plant (tt). what percent should be short?
50%
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
3/16
