To determine the probability of producing a homozygous dominant (BB) offspring from a cross between two rabbits with the genotype Bb, we can use a Punnett square.

  1. List the alleles from each parent:

    • Parent 1 (Bb): B, b
    • Parent 2 (Bb): B, b
  2. Set up a Punnett square:

        B      b
      ----------------
    B |   BB   |   Bb   |
      ----------------
    b |   Bb   |   bb   |
      ----------------
  1. Analyze the outcomes:

    • BB: 1 (homozygous dominant)
    • Bb: 2 (heterozygous)
    • bb: 1 (homozygous recessive)
  2. Total combinations: 4

    • BB = 1
    • Bb = 2
    • bb = 1

The probability of producing a homozygous dominant (BB) offspring is the number of BB outcomes divided by the total number of outcomes:

\[ \text{Probability of BB} = \frac{1}{4} \]

Thus, the correct answer is:

C 1 4

The men on the jury in "12 Angry Men" may not truly be the defendant's peers because their significant age difference, varied life experiences, backgrounds, and biases prevent them from fully understanding or empathizing with the challenges faced by a young man accused of murder, ultimately hindering their ability to impartially judge his circumstances.

The men serving on the jury in "12 Angry Men" might not genuinely represent the defendant's peers. Their significant age differences, diverse life experiences, and unique backgrounds create barriers to understanding the challenges of a young man accused of murder. Additionally, their personal biases can prevent them from empathizing with his situation, which ultimately affects their ability to impartially judge the case.

The men on the jury in "12 Angry Men" may not really be like the defendant. They are much older and have different life experiences, which makes it hard for them to understand what the young man is going through. Their different backgrounds can also affect how they see the case. This makes it tough for them to judge him fairly.
