Question

black spots red - to - black spots red spots this punnett square shows a cross between two holsteins. what is the probability that a holstein produced by this cross will have red - to - black spots? % submit

Explanation:

Step1: Count the total number of offspring

There are 4 boxes in the Punnett square, so the total number of possible offspring is \(n = 4\).

Step2: Count the number of offspring with red - to - black spots (\(m^{r}m^{r}\))

From the Punnett square, the number of \(m^{r}m^{r}\) offspring is \(m = 1\).

Step3: Calculate the probability

The probability \(P\) is given by the formula \(P=\frac{m}{n}\times100\%\). Substituting \(m = 1\) and \(n = 4\) into the formula: \(P=\frac{1}{4}\times100\%=25\%\)

Answer:

\(25\)
