Independent Assortment

Nondisjunction: Is the result of a mistake at the level of chromosome segregation, which involves the spindle fibers.

Recessive Genes: A recessive gene is a gene that can be masked by a dominant gene. In order to have a trait that is expressed by a recessive gene, such as blue eyes.

Dominant Genes: is a stronger trait

Somatic Cell none genetic cells

Germ cell: is a cell containing half the number of chromosomes of a somatic cell and able to unite with one from the opposite sex to form a new individual

karyotype: 21 figures shows the chromosomal arrangement

genotype: makes the traits within a gene or the genetic makeup of a specific organism.

colorblindness: mess up in the genetic gene mostly happens to males

Down Syndrome: mess up in the 21'st chromosome. if you have 2 lines your don't have down syndrome and if you have 3 lines in the 21'st then you have down syndrome

Turner's disease: mess up in the x and o. they are asexual. and you'll see a X and an O.
