Solution

The genotypes that would give the offspring brown eyes are BB and Bb. This is because brown eyes (B) are dominant over blue eyes (b).

Here's a step-by-step explanation:

  1. BB: This genotype means the individual has two dominant genes for brown eyes. Therefore, the individual will have brown eyes.

  2. Bb: This genotype means the individual has one dominant gene for brown eyes and one recessive gene for blue eyes. However, because brown is dominant, the individual will still have brown eyes.

The genotype bb would result in blue eyes, not brown, because there are two recessive genes and no dominant gene to override them.
