This online tool calculates Punnett Square diagram that can be used to to predict an outcome of a particular cross or breeding experiment. Enter each parent's genotype, using capital letter for the dominant allele and lowercase letter for the recessive allele. Use different letters to mark different genes, for example A for the first gene and B for the second one to avoid mix-ups. If you want to use Punnett Square to calculate your child's eyes or hair color, check out Child's Traits tool instead.

It is based on Punnett Square method but uses two levels of heredity parents and grandparents and trait distribution statistics to improve prediction quality.

Grade Levels: Subject Matter: Biology, Physical Anthropology, Genetics Time Allotment: class sessions Description: This lesson plan explores the genetics and evolution of skin color, using a short story by Kate Chopin called "Desiree's Baby" as a starting point.

It is a story of race and gender in antebellum Louisiana. Desiree is deeply in love with her husband, Armand, and he is a loving husband and a proud father until he notices their infant's dark skin.

Because Desiree was abandoned as a child, her ancestry is unknown. Armand concludes that she is not white and tells her to leave. His rejection drives Desiree to take her own life and that of the baby. In the last line of the story, Armand discovers that he is also of mixed ancestry.

Students read the story and then discuss a set of questions about genetics probing the puzzle of how Desiree's baby can have a darker skin color than either Desiree or the baby's father, Armand. Finally, students will read assigned background articles and write an analytical essay scrutinizing various theories accounting for the evolution of different skin colors.

The case was developed for urban community college students in their first semester of general biology. The course curriculum is organized around the general theme of evolution. By the time the case is introduced, students have covered evolution, biochemistry, cell biology, and Mendelian genetics.

The case is also appropriate for anthropology and biology courses for non-majors. Have the students work in small groups to answer the questions at the end of the short story handout.

The following Punnett square shows the possible offspring from a cross between two individuals of intermediate skin color. The offspring of this cross exhibit seven shades of skin color based on the number of dark skin alleles in each genotype. If you only have time to screen the segment on skin color, begin the video at with Stephen Jay Gould saying: "My favorite trivia question in baseball If you are using the DVD, go to scene 8.

You should have a good understanding of what phenotype and genotype mean, as well as what letter combinations make a genotype homozygous or heterozygous.

Scientists would make predictions based on observations of those traits, and then test out their ideas about the inheritance of a genetic trait by crossing the organisms in question and examining the offspring.

The traits that are passed from parents to offspring are determined by the combination of genes genotype that are in the gametes. The probability of a particular event occurring is the fraction of outcomes in which that event occurs. Examine the picture below that shows how sex chromosomes are inherited from parents. Is it the father or the mother?

Answer: The father. The father contributes either an X or a Y chromosome. The mother only contributes an X. Look at the diagram above again. Mom and dad already have three girls in their family. What is the probability that the fourth child with be a boy? What is the probability of rolling two fives with a pair of dice? Punnett is a chart drawn to determine the probable results of a genetic cross. The genes of the parents represented by assigned letters are written on the left-hand side and the top of the Punnett Square.

Alleles of each gene are separated above each column on the top or into rows on the bottom. For example if the letter Y represents the gene for pea pod color where yellow is dominant to green. One parent is heterozygous Yy and the other is homozygous yy, the completed Punnett Square would look like the one on the right. A completed Punnett square gives the probable outcome of a given cross. In this case, the probability of each phenotype green vs. We can write these offspring probabilities as ratios to simplify our results:.

In this section, follow the tutorial so that you can learn how to set up your own Punnett squares to solve genetics problems. You will use this skill for the rest of the module, so take your time.
