Question

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

Answer 1

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
