Question

A group of scientists is exploring the nest building behavior of two closely related bird species, A and B, where females of the species construct nests. Species A females construct nests using twigs, and Species B females build their nests using birch bark. In order to assess the relative important of genes vs. the environment in nest building behavior, the researchers perform a cross-fostering experiment and observe the nest building behavior of the offspring after they reach adulthood. Below are the three types of clutches (groups of bird offspring) included in the experiment. Multiple clutches of each type were observed. For the clutches that included foster chicks, only the fostered chicks' behaviors were assessed 1) undisturbed clutches (no chicks transferred in or out) 2) "same fostered" clutches (included chicks fostered by a different mother of the same species) 3) cross-fostered clutches (included chicks born to a mother of the other species) Part A Select ALL the clutch conditions that allowed the scientists to assess the alternative hypothesis that simply being raised by a foster mom affects nest building behavior in these species of birds. Species A chicks in undisturbed clutch Species B chicks in undisturbed clutch Species A chicks fostered by Species A mom (same fostered) Species B chicks fostered by Species B mom (same fostered) Species A chicks fostered by Species B mom (cross-fostered) Species B chicks fostered by Species A mom (cross-fostered) SubmitPrey Previous Answers Request Answer

Explanation / Answer

Option A, B, C, D allowed the scientists to assess the alternative hypothesis that simply being raised by a foster mom affects nest building behaviour in these species of bird.

Because according to the research, it has shown in cross fostering that, individual's nest did not resemble that of their foster mother, and hence the nests they built did not resemble that in which they were reared.

So, first four options support alternate hypothesis.
