This question is incomplete, the complete question is;
You have two strains of mice, one is inbred and the other is genetically heterogeneous. You examine weight differences for the mice when they are raised in the same environment. If the total variance for the inbred strain is 0.5 square ounces and total variance for the heterogeneous strain is 0.7 square ounces, what is the relative amount of variance due to genetic variation
?
Multiple Choice
A. 0.2 square ounces
B. 0.5 square ounces
C. 0.7 square ounces
D. 1.2 square ounces
Answer:
Option A) 0.2 square ounces is the correct answer
Step-by-step explanation:
Given that;
two strains of mice where raised in the environment and while one is inbred, the other is genetically heterogeneous.
The total variance for the inbred strain = 0.5 square ounces
total variance for the heterogeneous strain = 0.7 square ounces
relative amount of variance due to genetic variation = ?
The relative amount of variance due to genetic variation can be gotten by taking the difference of the total variance of both mice
so;
relative amount of variance due to genetic variation = variance for the heterogeneous strain - total variance for the inbred strain
we substitute our values
relative amount of variance due to genetic variation = 0.7 - 0.5
relative amount of variance due to genetic variation = 0.2 square ounces.
Therefore Option A) 0.2 square ounces is the correct answer
