Answer:
A. nutrition
Explanation:
The most likely explanation for the remainder of the variation would be nutrition. Little is known about how exactly nutrition affects genetics and heritability, but it is known that it does. Scientists believe that traits that allow a species to feed more successfully have a drastically increased chance of appearing in offspring as it greatly contributes to their survival. When a trait does not allow the species to gain the proper nutrition, the species tends to develop other traits to accomplish this which then get passed on to offspring.
Knowing that
purple flowers are dominant (have a higher percentage of passing certain information to offspring) and white a recessive (have a much lower chance of passing certain information to offspring) the plants of the
generation (first generation bread) will be all purple.
When a white-flowered pea reproduces with a purple-flowered pea all of the offspring will be purple.
When 2 offspring (purple-flowered) of the
generation breed, there is a 15% percent chance of offspring being white-flowered.

Giraffes probably used to have short necks. Over time, since the branches of trees or plants were out of their reach, they adapted to this by having a longer neck. Those with longer necks are able to reach the food and eat it that those with short necks could not. Obviously, those with longer necks are able to survive and therefore reproduce. Because of reproduction, they are able to pass on this characteristic that allowed them to survive on to their offspring. This leads to offspring doing the same and over time, affecting the entire population of giraffes and soon evolving giraffes. This is natural selection doing its work in the evolution of long necks in giraffes.
Monogamous pine voles and polygynous montane voles are different in terms of the parental care.
<h3>
Monogamous Pine voles vs Polygynous Montane voles ;</h3>
Monogamous Pine vole do extended biparental care, whereas Polygamous Montane voles do not form long-lasting pair bonds and they engage in extended biparental care.
Monogamous species has the prairie vole, vasopressin facilitates affiliation, pair-bonding, and paternal care.
Polygamous Montane vole's vasopressin fails to influence social behavior.
