Use this information for questions 1-4: In tomatoes, red fruit (R) is dominant over yellow fruit (r). A plant that is homozygous for red fruit is crossed with a plant that has yellow fruit.

Perform a Punnett square and then find the probability of each predicted genotype and phenotype appearing in the F1 generation.

Some diseases are passed from parents to offspring through their genes, these are considered genetic diseases. Some of the inherited disorders that fall into this category include Tay-sachs disease, sickle-cell anemia, hemophilia, and cystic fibrosis. A child can suffer from one of these diseases only if both parents pass on a recessive gene for the disease. Cystic Fibrosis results in the body producing abnormally thick, sticky mucus which clogs the lungs leading to recurring infections.

Dominant		having two of the SAME version of a gene (dominant or recessive)
Gene		having two DIFFERENT versions of a gene
