being able to roll the tongue is dominant over not being able to roll the tongue. what is the probability that the offspring will be unable to roll the tongue? 0 2 3 4
Answer
Explanation:
Step1: Analyze the Punnett - square
The Punnett - square shows 4 offspring genotypes: Rr, Rr, Rr, Rr.
Step2: Determine non - rolling genotype
The genotype for not being able to roll the tongue is rr. There are 0 rr genotypes in the Punnett - square.
Step3: Calculate probability
The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes (offspring with rr genotype) is 0, and the total number of outcomes is 4. So $P = \frac{0}{4}=0$.
