1. What is a Punnett Square? A tool for showing possible alleles of offspring in a test cross A tool for showing possible gametes of parents in a test cross A tool for showing possible alleles of parents in a test cross 2. In a Punnett Square, the dominant character or allele is repre...

When a Punnett Square Will Not Be Useful Punnett squares are helpful much of the time, even when comparing multiple traits or ones with complex dominance relationships. But sometimes predicting phenotypic outcomes can be a difficult practice. For example, most traits among complex life forms involve...
A common Punnett square is amonohybridcross(Adjust the slider to 1 in the activity below). This type of cross tracks one gene. Both parents are heterozygous (that is, they both have one dominant,A,and one recessive,a,allele for the trait). From the Punnett square, the following conclusion...
What is a monohybrid cross and a dihybrid cross? Draw the Punnett square showing the cross between the F1 female and the homozygous recessive male, making sure to draw all possible unique gametes from each individual, showing chromosomes, alleles, and the location of alleles. Last...
Draw a Punnett square to demonstrate the possible progeny that will result from the following cross: \rm BBFf \times bbFF. Using the Punnett square to demonstrate the phenotypic and genotypic ratio of F1 and F2 derived from a dihybrid cross between ...

Dihybrid cross inDrosophila An example of a 4×4 Punnett square can be observed in the dihybrid cross between the long-winged and black-bodied Drosophila and a vestigial-winged, grey-bodiedDrosophila. The cross produces 9 long-winged grey-bodied, 3 long-winged black-bodied, 3 vestigial-winged...
Moreover, our Punnet square maker allows you to calculate the probability that a rare, recessive genetic disease will be inherited. Hey, perhaps you're looking for a more advanced dihybrid cross calculator (with 2 traits and 4 alleles), or an extreme, gigantic trihybrid cross calculator (a ...
