Q) A broad sense heritability figure which shows the relationship- between parental egg size and offspring egg size has an r2 value of 0.1225, would natural selection act upon the egg size?
- The value means that offspring do not resemble parent, any change is due to environment. so will natural selection act on the egg size trait? why or why not pls explain in detail
Answer- Yes, according to current observation, natural selection is working in case of egg size trait.
Explanation- Natural selection is the process of selection of more adaptive phenotype by nature in comparison to less adaptive phenotype.
In this case, it has been observed that average fitness of individuals increased with egg size and also inbreeding depression is also declined with egg size. A consequence of this is that populations that differ in mean egg size have experienced different magnitudes of inbreeding depression (all else being equal) and thus differ from others in the magnitude of selection.
