A geneticist is studying two genes. Each gene can be either dominant or recessive. A sample of 100 individuals is categorized as follows.

$\begin{array} { c c c }
& \begin{array} { c }
\text { Gene 2 } \
\text { Dominant }
\end{array} & \begin{array} { c }
\text { Gene 2 } \
\text { Recessive }
\end{array} \
\text { Gene 1 Dominant } & 4 & 6 \
\text { Gene 1 Recessive } & 36 & 54
\end{array}$

What is the probability that in a randomly-sampled individual, gene 1 is dominant?
A) 0.10
B) 0.04
C) 0.90
D) 0.40

Quizplus · Accepted Answer

The probability that gene 1 is dominant is calculated by adding the individuals with a dominant gene 1 (4 + 6) and dividing by the total sample size (100), resulting in 10/100 or 0.10.
