Genetics Flashcards

Front

Different forms of the same gene

Back

Alleles

Front

An allele whose trait is always expressed in the organism when the allele is present

Back

Dominant allele

Front

A sequence of DNA with instructions for a trait; passed from parent to offspring through the process of reproduction

Back

Gene

Front

The difference in DNA among individuals

Back

Genetic Variation

Front

An organism’s unique genetic makeup. Example: specific allele combination of an organism

Back

Genotype

Front

The passing of traits from parents to offspring

Back

Heredity

Front

Having two different alleles for a particular gene

Back

Heterozygous

Front

Having two identical alleles for a particular gene

Back

Homozygous

Front

An organism’s expressed or physical traits. Example: blood type, hair or eye color

Back

Phenotype

Front

An allele whose trait is not expressed when the dominant allele is present

Back

Recessive allele
