Choose the statement below that best describes the relationship between the structures.
Chromosomes are structures found in the nucleus of a cell. Chromosomes are made up of long strands of DNA. Genes are segments of DNA on a chromosome.
Genes are structures that are made up of long strands of DNA. Chromosomes are segments of DNA that contribute to the inheritance of a particular trait.
DNA is made up of many chromosomes. Each chromosome has one gene that codes for a specific trait in an organism.
Genes are large structures that help chromosomes manufacture DNA in an organism.

Two students use beads to model traits being passed from one generation to the next. They place one red bead (dominant allele) and one white bead (recessive allele) in a bag labeled“Alleles for Parent A” and the same in a bag labeled “Alleles for Parent B.” What should they do next to create the best model?
Look into the first bag, pick a red bead. Then, look into the second bag and pick a red bead.
Without looking, pick a bead from the first bag. Then, look in the second bag and pick the same color as they chose from the first.
Without looking, pick one bead from the first bag. Then, without looking, pick a bead from the second bag.
Without looking, pick one bead from the first bag and drop it into the second bag. Then, pick two beads from the second bag.
