Chromosome - Wikipedia
A chromosome (/ ˈ k r oʊ m ə ˌ s oʊ m, -ˌ z oʊ m /; from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material of an organism.Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable ...
Y chromosome - Wikipedia
The Y chromosome is one of two sex chromosomes in mammals, including humans, and many other animals.The other is the X chromosome.Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction.In mammals, the Y chromosome contains the gene SRY, which triggers testis development.

How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. First, there's less DNA in a sperm cell than there is in a non-reproductive cell such as a skin cell.

the genetically inherited condition in which there is a marked deficiency of pigmentation in skin, hair, and eyes. An individual with these traits is an "albino."
This exercise is a simulation of human karyotyping using digital images of chromosomes from actual human genetic studies. You will be arranging chromosomes into a completed karyotype, and interpreting your findings just as if you were working in a genetic analysis program at a hospital or clinic.
