Question

in a group of sheep, some individuals have white wool and others have black wool. in this group, the gene for the wool color trait has two alleles. the allele for black wool (l) is recessive to the allele for white wool (l). this punnett square shows a cross between two sheep. what is the probability that a sheep produced by this cross will have black wool? %

Explanation:

Step1: Identify black wool genotype

Black wool is recessive, so only the genotype $ll$ produces black wool.

Step2: Count total and favorable outcomes

Total Punnett square outcomes: 4. Favorable ($ll$) outcomes: 1.

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{1}{4}$

Step4: Convert to percentage

$\frac{1}{4} \times 100 = 25$

Answer:

25%
