Draggable itemCorresponding Item
Gene
a form of a gene; genetic variety that can give phenotypic variety
Phenotype
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
Allele
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.

1

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.

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

Draw the cross between a snail that is heterozygous for white shell and a snail with a black shell.

1

If a snail with heterozgyous for white shell and a snail with a black shell are crossed. What percent of the offspring will have a white shell?
