Quizplus · Accepted Answer

If Beau's parents each carry a dominant gene for brown eyes and a recessive gene for blue eyes, they are both heterozygous for eye color (Bb). When two heterozygous individuals mate, the probability of their offspring inheriting two recessive (b) genes and having blue eyes is 25% or 0.25. Therefore, the correct answer is D) 0.25.
