Nondisjunction: This is the chromosomal mutation that produces an offspring with an incorrect number of chromosomes. An example of nondisjunction is when a cell with 5 chromosomes and a cell with 3 chromosomes is produced.
Recessive Genes: This is when a trait can be carried in a persons genes but not shown. An example of a recessive gene is when a mom has blue eyes and a dad has brown, the baby has brown eyes so the moms blue eyes are recessive.
Dominant Genes: This is when a trait can be carried in a persons genes but is shown as a physical trait. An example of a dominant gene is when a mom has blue eyes and a dad has brown, the baby has brown eyes so the dads brown eyes are dominant.
Somatic Cell: Any cell of a living organism other than the reproductive cells. 3 examples of somatic cells are Eosinophil, Gila cell, and the Hepatocyte.
Germ Cell: A cell containing half the number of chromosomes of a somatic cell and able to unite with a gamete. Examples of a germ cell is an egg or sperm.
Karyotype is a visual display on an individual's chromosomes, which are paired and numbered. A genotype is the complete set of genes carried by an organism. This can change a phenotype which is the set of traits in an organism.
