Question

The chromosome theory of inheritance is based on the claim that genes are found on chromosomes. If you were going to build a physical model of a chromosome from everyday materials to demonstrate meiosis (including crossing over), which of the following would work best? strings of pop beads (each bead is a gene) a six-pack of soda with the cans held together by plastic rings string or twine (each length of string is one chromosome) pipe cleaners (each pipe cleaner is one chromosome) What is a genetic locus? A chromosome that contains genes. An allele of a gene. A particular position on a chromosome.
