Sock+Karyotype

Creating a "Sock Karyotype." 1. Separate the socks. 2. Sort the socks into pairs based on their stripes. (Bends or shape doesn't matter.) 3. Arrange the pairs from longest to shortest. (Put the mismatched pair at the end.) 4. Attach the pairs to a piece of paper in rows from longest to shortest with the mismatched pair at the end.



Additional information: Chromosomes can be compared to socks because they come in pairs. A sock could be made from one long piece of yarn and similarly a chromosome contains one long piece of DNA. Chromosomes are the pieces of DNA (and supporting proteins) found in the nucleus of a cell. Chromosomes occur in pairs. Each chromosome of the pair comes from a different parent. Different sections of DNA in a chromosome contain the code for the different traits in an organisms. Arranging chromosomes in pairs and by length is called a karyotype.
