Different Versions of the same gene.

Chromosomes in which one set comes from mom and one set comes from dad.

Having two of the same alleles. ex. (AA, aa)

Having two different alleles ex. (Rr)

An allele if present, will always have that trait expressed. (seen)

An allele that will only have the trait expressed (seen when dominant allele is not present.

The alleles you inherit. ex. The alleles for eye color.

The physical traits (characteristics) seen in an organism. ex. Red hair

A diagram that shows the probability of inheriting traits from parents with certain genes. (alleles)

The assortment of chromosomes for one trait doesn‘t affect the assortment of chromosomes for another trait.

When chromosomes separate in meiosis, each gamete (egg or sperm) will receive only one chromosome from each pair.

A dominant (strong) allele will express itself over a recessive (weak) allele.

Genes are located on chromosomes and the behavior of chromosomes during meiosis accounts for inheritance patterns.

A form on inheritance in which one gene is capable of interfering with expression of another.

The process by which genetic information is passed on from parent to child.

An individual who is capable of passing on a genetic mutation associated with a disease and may not display disease symptoms.

One characteristic is controlled by two or more genes. Ex. Skin color, height, eye color)

When the phenotypes of the two parents blend together to create a new phenotype for their offspring. Ex. (White flower crossed with Red flower produces Pink offspring.)

When the two parent phenotypes are expressed together in the offspring. Ex. (when White flower is crossed with Red flower produces white and red flowered offspring.

Traits that are found on either one of the chromosomes that determine sex, or the sex chromosomes. Ex. (color blindness, Hemophilia,)

A diagram that depicts the biological relationships between an organism and its ancestors.
