Answer:

The probability that both are in the same gamete is 0.25

Explanation:

Given


P(S) = 50\%


P(T) = 50\%

Required

Determine the probability that both are in same gamete

The required probability means: P(S and T)

This is then calculated as:


P(S\ and\ T) = P(S) * P(T)

Substitute values for P(S) and P(T)


P(S\ and\ T) =50\% * 50\%

Convert to decimal


P(S\ and\ T) =0.50* 0.50


P(S\ and\ T) =0.25
