Genetics Vocab

The passing of traits from parent to offspring is ______________.

• Genetics

• Dominant Gene

• Heredity

• Allele

A distinguishing quality that can be passed from one generation to another.

• Recessive Gene

• Punnett Square

• Trait

• Heterozygous

A gene that prevents the other gene from showing up physically. Represented by a capital letter. (Example Rr or RR)

• Dominant Gene

• Phenotype

• Genetics

• Parent

A gene that does not show up physically even though it is present. Represented by a lowercase letter. (Example: rr or bb).

• Homozygous

• Generation

• Heredity

• Recessive Gene

Segments of DNA that carry hereditary instructions and are passed from parent to offspring; located on chromosomes.

• Alleles

• Genes

• Genotype

• Dominant Gene

Different forms of a single gene. (Example: blue eyes, brown eyes, green eyes).

• Alleles

• Punnett Square

• Trait

• Genetics

The combination of genes an organism receives from the parents (actual genetic makeup).

• Phenotype

• Heterozygous

• Genotype

• Parent

Physical appearance resulting from genetic make-up; what it looks like.

• Phenotype

• Recessive Gene

• Trait

• Heredity

This is a tool used to visualize all the possible combinations of alleles from parents.

• Alleles

• Punnett Square

• Generation

The study of the inheritance of traits.
