passing of traits to the next generation

specific characteristic of an organism.

functional unit that controls inherited trait expression that is passed on from one generation to another generation.

alternative form that a single gene may have for a particular trait.

organism heterozygous for a specific trait.

consistently producing offspring with the same trait.

Mendelian law stating that two alleles for each trait separate during meiosis.

organism with two of the same alleles for a specific trait.

organism with two different alleles for a specific trait.

observable characteristic that is expressed as a result of an allele pair.

Mendel’s name for a specific trait that appeared in the F1 generation.

Mendel’s name for a specific trait hidden or masked in the F1 generation.

a genetic cross used to determine the unknown genotype of an organism displaying a dominant phenotype.

diagram used to predict the possible offspring of a cross between two known genotypes.

complex inheritance pattern that occurs when neither allele is dominant and both alleles are expressed.

complex inheritance pattern in which the heterozygous phenotype is intermediate between those of the two homozygous parent organisms.

characteristic, such as eye color or skin color, that results from the interaction of multiple gene pairs.

having more than two alleles for a specific trait.

law of independent assortment

Mendelian law stating that a random distribution of alleles occurs during the formation of gametes.

traits controlled by genes located on the sex chromosomes.

individual heterozygous for a recessive disorder such as cystic fibrosis or Tay-Sachs disease.

diagrammed family history that is used to study inheritance patterns of a trait through several generations and that can be used to predict disorders in future offspring.
