Chapter 53, Problem 1DA
Summary Introduction
To determine: The approximate mean number of errors that changed from prenatal population to the seventh generation of fast rat population. Also, determine the type of selection in this form of heredity.
Introduction: The rats were intentionally mated through the selective breeding to demonstrate the particular
Expert Solution & Answer
Explanation of Solution
The behavioural variation in the rats was determined by an experiment throughout several generations. The rats that have a genetically diverse group to find the maze by making few errors were labeled with bright, and those who were error-prone were labelled dull. The mating was performed between bright-bright, and dull-dull rats upto the seven generations. The scientist concluded that both types of rats remained genetically separate. The dependent variables concluded the mean number of errors that were made in rats in several trials. The further mating of the dull mother with bright offspring concluded that bright rats were making lesser errors than the dull rats.
The experiment was performed through the artificial selection of the rats that demonstrated the flexibility in the learning ability of rats in response to the environmental factors.

In addition, we know that the additive genetic covariance between wing and leg length is 0.60 mm2. What is the expected evolutionary change in mean leg length due to selection on both wings and legs?

I found that this trait follows Mendelian genetics with a single locus having two alleles: BB (large mimic), Bb (small mimic), and bb (no mimic).
