This is the basis of the Punnett square - line up the possible reproductive cells for one parent along the top of the square, and the possible reproductive cells for the other along the left side of the square, then combine them in the middle to show all possible combinations of alleles ...
In both cases, the phenotype will be whatever the dominant gene is. In order for a recessive trait to show, it would have to be homozygous recessive, meaning both genes are recessive. Read Punnett Square | Definition & Overview Lesson ...
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 ...

Bb (brown hair) are heterozygous meaning that they have two different alleles for the gene. Some crosses may only give you one or two genotypes. For our example, using the cross BB x Bb, the Punnett square would show the possibilities as two BB and two Bb. If you cross two ...
