Final answer:

A Punnett square is a useful tool in genetics to predict the possible outcomes of a genetic cross. Using the alleles from the male and female bears, we can create a Punnett square for their offspring in the F1 generation. The resulting Punnett square shows the possible genotypes and phenotypes.

Step-by-step explanation:

A Punnett square is a useful tool in genetics to predict the possible outcomes of a genetic cross. In this case, we have a male and female bear with black fur, both of whom are heterozygous for the trait (Bb). To create a Punnett square for their offspring (F1 generation), we need to cross the alleles from both parents.

Step 1: Write the possible alleles from one parent along the top of the square (B and b).

Step 2: Write the possible alleles from the other parent along the left side of the square (B and b).

Step 3: Combine the alleles from the top and left side to fill in the boxes of the Punnett square.

The resulting Punnett square will show the possible genotypes and phenotypes of the offspring.

In this case, the F1 generation will have a 25% chance of being homozygous dominant (BB), 50% chance of being heterozygous (Bb), and 25% chance of being homozygous recessive (bb). All of the offspring will have black fur because black fur is the dominant trait.
