Phenotype Physical appearance determined by genotype.
Allele Any of the alternative forms of a gene that occurs at a specific place on a chromosome
Trait Characteristic that is inherited.
Chromosome Long, continuous thread of DNA that consists of numerous genes an regulatory information.
DNA Molecule that stores genetic information in al organisms
Heterozygous Characteristic of having two different alleles that appear at the same locus of sister chromatids
Recessive Allele that is not expressed unless two copies are present in an organisms genotype
Cross Mating of two organisms
Dihybrid Cross, or mating, between organisms involving two pairs of contrasting traits
Dominant Allele that is expressed when two different alleles are present in an organisms genotype
Genotype Collection of all of an organisms genetic information that codes for traits
Homozygous Characteristic of having two of the same alleles at the same locus of sister chromatids
Monohybrid Cross, or mating, between organisms that involves only one pair of contrasting traits
Genome All of an organisms genetic material
Purebred Type of organism whose ancestors are genetically uniform
Phenotype Collection of all of an organisms physical characteristics
Homologous chromosome Chromosomes that have the same length, appearance , and copies of genes, although the alleles may differ
Incomplete dominance Heterozygous phenotype that is a blend of the two homozygous phenotypes
Codominance Heterozygous genotype that equally expresses the traits from both alleles
Carrier Organism whose genome contains a gene for a certain trait or disease that is not expressed in the organisms phenotype
Sex-linked gene Gene that is located on a sex chromosome
Polygenic trait Trait that is produced by two or more genes
Epistasis A gene that interferes with the expression of other genes
Pedigree Chart of the phenotypes and genotype in a family that is used to determine whether an individual is a carrier of a recessive allele

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
