Gene
The inherited bits of information that are passed directly from the parent's cells to the child's cells
A section of DNA
Allele
Different or alternative forms of genes.
Dominant Gene
A trait that appears in the offspring.
Type of gene that is stronger and appears more often.
Recessive Gene
A trait this is hidden in the offspring.
Type of gene that is weaker and appears less often.
Homozygous
An organism that has two identical alleles for a trait
Heterozygous
An organism that has two different alleles for a trait
Genotype
The gene's that an organism has that make up it's traits.
An organism's genetic makeup or allele combinations.
Phenotype
An organism's physical appearance, or visible traits.
Breeding
The producing of offspring through mating.
Punnett Square
A chart that shows all the possible combinations of alleles that can result from a genetic cross.
Tool scientists use to predict the likelihood of certain traits. Anytime a dominant gene appears, the offspring will have the dominant trait.
Lowercase letter
Recessive genes are always represented by this type of letter.
Uppercase letter
Dominant genes are always represented by this type of letter.
Offspring
A new organism produced by one or more parents.
