Draggable item		Corresponding Item
Allele		a form of a gene; genetic variety that can give phenotypic variety
Gene		a section of DNA that contains the directions for synthesizing a protein
Dominant		the form of a gene that can mask the other
Genotype		the form of a gene that can be covered up when present with another form
Phenotype		the way an organism looks
Recessive		the genetic make up of an individual
Heterozygous		having two of the SAME version of a gene (dominant or recessive)
Homozygous		having two DIFFERENT versions of a gene

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.

1

What would be the genotypes and phenotype for the homozygous red plant?

1

What would be the genotypes and phenotype for the homozygous yellow plant?

1

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

What is the probability of the parents in cross above resulting in a tomato plant offspring that is homozygous?

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. 

1

If an individual has the genotype FF will they have cystic fibrosis?

1

If an individual has the genotype Ff will they have cystic fibrosis?

1

If an individual has the genotype ff will they have cystic fibrosis?
