Summary Introduction

To determine: Whether it is worth to develop a population of Drosophila that has an olfactory mutation by artificial selection with the reason for the same.

Introduction:

In Drosophila, flies were trained to avoid certain olfactory cues. A mean of 8.5 trials was required for one population. A subgroup of this parental population that was trained most quickly, having a mean value of 6.0 was interbred, and their progeny were examined. These flies demonstrated a mean value of 7.5. The flies obtained has a realized heritability of 0.4.

In the F2 generation, 306 rabbits with red eyes and 71 with a white eye phenotype suppose the calculated x2 value is 0.35. Find the x2 range using the distribution chart. What is the p-value range? using these information do you accept or reject the null hypothesis? The distribution chart is attached below.
In an assessment of learning in Drosophila, flies were trained to avoid certain olfactory cues. In one population, a mean of 8.5 trials was required. A subgroup of this parental population that was trained most quickly (mean = 6.0) was interbred, and their progeny were examined. These flies demonstrated a mean training value of 7.5. Calculate realized heritability for olfactory learning in Drosophila.
The narrow-sense heritability of wing length in a population of Drosophila melanogaster is 0.8. The narrow-sense heritability of head width in the same population is 0.9. The genetic correlation between wing length and head width is −0.86. If a geneticist selects for increased wing length in these flies, what will happen to head width?
