= A chromosome is a rod-like strand of DNA that carries genetic information and is found in the  nucleus of a cell. Within our bodies we all possess 46 chromosomes that make up the building blocks of who we are. When we are first concieved as a single cell zygote, we inherite 23 chromosomes from our mother and 23 from our father. There are two main types of chromosomes that make up our physical structure. Those chromosomes are autosomes & sex chromsomes. Autosomes deal with things like our eye color, height or genetic predispostions to health problems and can be either recessive or dominant. Sex chromosomes deal with whether we are male or female. These sex chromosomes come in pairs of XX and XY. If we are born with XX chromosomes it means you will be born a female. If we are born with an XY set then we are male. In regards to recessive genes only a mother can pass down characteristics to her son and daughters can only recieve traits from a mother if she carries a recessive gene on her X chromosome. Chromosomes are what some might call organized chaos since we know what each set is responsible for in human development, but at the same time the results are entirley random as to what traits your child will be born with.The pairs of chromosomes combine randomly creating variation, which is intergral to healthy human development. During Meiosis, sometimes parts of the chromosomes may break and reattach to other chromosomes. Other times during meiosis the chromosomes finally count may be 24 or 22. This may result in Down Syndrome which is an abnormality of autosomes. Abnormalities of sex chromosomes can also create developements such as Turner Syndrome. A proper human developement relies heavily on whether or not our chromosome count is 46. media type="custom" key="12404940"Behavior of Chromosomes
