• belong to the same species

• Have to range great distances to eat

• Have identical DNA

What are chromosomes?

• They are thread like structures containing DNA found inside the nucleus of our cells

• They are X shaped blobs made of ribosomes

• They are the inherited traits we recieve from our parents

• They are types of alleles found in the mitochondria of a cell

What is a gene?

• An entire chromosome.

• A small part of DNA found in a chromosome that gives our body instructions to build for a specific trait that we have

• Things that are sometimes refered to as XX and XY inside of our cell membranes

• Kind of like a "flavor" because there are 23 kinds from each parent.

What is a Chromosome?

• a threadlike structure found in the nucleus of most living cells, carrying genetic information in the form of genes.

• An X shaped thing found in the mitochondria of the cell that helps create energy in the form of ATP.

• A threadlike structure found in the lysosome carrying genetic information in the form of proteins.

• A colorful and fluorescent type of sugar that our body uses to break down and get energy.4
