What is a chart that shows the possible gene combinations called?

The correct answer is the Punnett square. The chart that shows the possible gene combinations is called a punnet square. It is a square diagram that is used to represent the possible genotype of offspring from their parents. The tool represents a visual representation of Mendel’s experiment. This square diagram was devised by an English Scientist, Reginald C. Punnett, in the twentieth century, and it was named after him.

Punnett square is commonly used by biologists and scientists to determine the genotype of offspring. The Punnett square gives all the possible genetic outcomes of what two individuals will produce when crossed. It is one of the easiest ways to calculate the probability of inheriting a particular trait. Punnett square can be set up easily by drawing a grid of perpendicular lines then put one parent genotype cross the top and the other on the left side.
