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 statement would work best?

The question is incomplete as it does not have the options which are:

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)

strings of pop beads (each bead is a gene)

strings of pop beads (each bead is a gene)

Explanation:

The Chromosomal theory of inheritance was proposed by Thomas Hunt Morgan when he found from his experiments that the trait determining factors called genes are present on a structure called genes.  He was able to conclude this when he got the recombined phenotype in the offspring.

If we want to explain the model with the household things then we should choose a string made of the pop beads in which each pop bead can be represented as a gene. These beads can be easily rotated which can demonstrate the mechanism of recombination in a chromosome.

Thus, the selected option is correct.

what's the question ?
