Should be 3. This is biology not english- and the gametes normally contain half is what I was taught.
Answer: Some potential traits of an offspring of two heterozygous parents with traits for brown hair, B, and blonde hair, b, include brown and blond. Since both parents are heterozygous, the genetic traits would be Bb and Bb. Also since the B (brown) is the dominant trait, the likelihood of a brown-haired offspring is three-fourths more likely than a blonde offspring. All the genetic possibilities are BB (brown), Bb (brown because of the dominant trait), Bb (brown), and bb (blonde).
