Question

why does tt occur 50% of the time? 0.75 - 0.25 = 0.50 4 x 0.125 = 0.50 0.25 + 0.25 = 0.50 50% x 1 = 50%

Explanation:

Step1: Analyze the Punnett square

In the given Punnett square, there are 4 possible genotypes: TT, Tt, tT, tt.

Step2: Count the occurrences of Tt - like genotypes

Tt and tT are both heterozygous genotypes. There are 2 out of 4 boxes that have either Tt or tT.

Step3: Calculate the probability

The probability is calculated as the number of favorable outcomes (2) divided by the total number of outcomes (4). So, \( \frac{2}{4}=0.5 = 50\%\). This is equivalent to \(0.25 + 0.25=0.50\) (since each of Tt and tT has a probability of \(0.25\)).

Answer:

\(0.25 + 0.25 = 0.50\)
