Question

Genes S and T are not linked. If there is a 50% probability that allele S is in a gamete and there is a 50% probability that allele T is in a gamete, what is the probability that both are in the same gamete

Answer 1

Answer:

The probability that both are in the same gamete is 0.25

Step-by-step 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

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

$P(S\ and\ T) =0.25$
