Independent Assortment By: Taylor Mcknight

Meiosis and Mitosis

The end result of both are daughter cells produced from a parent cell. Meiosis has two steps of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical.

Nondisjunction- The failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division.

Recessive Genes- A recessive gene is a gene that is a dominant gene. In order to have a trait by a recessive gene, such as blue eyes you have to get if from your parents.

Dominant Genes- A dominant gene is a segment of DNA information that is used to make chromosomes

Somatic cell- any cell of a living organism other than the reproductive cells.

Germ cell- A cell that has half the number of chromosomes of a somatic cell and is able to unite with one from the opposite sex to form a new individual; a gamete.


The number and visual appearance of the chromosomes in the cell nuclei of an organism or species.

Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.


the way genetic information in written and the PAttern.


The way a genetic trait is physically shown or seen in an organism.

Kleinfetter's syndrome- A syndrome affecting males in which the cells have an extra X chromosome (in addition to the normal XY. The disorder is neither dominant or is usually the cause of non- disjunction of sex chromosomes during meiosis.

Down Syndrome- A genetic chromosome 21 disorder causing developmental and intellectual delays. they can be inherited in different ways: autosomal dominant, autosomal recessive, X-linked or Y-linked.

Color blindness- A reduced ability to distinguish between certain colors. red-green color blindness is a sex linked recessive trait and blue-yellow color blindness is a dominant trait.

Turner's disease- Turner syndrome, a condition that affects only girls and women, results when a sex chromosome (the X chromosome) is missing or partially missing. Turner Syndrome is neither dominant nor recessive. This is because the chromosomal pair would be XO instead of XX like it should be.
