Which of the following demonstrates the pattern of development in Greylag Geese?
Which of the following demonstrates the pattern of development in Greylag Geese? {Please give specific answers, which among the following gives the best available demonstration?, If needed, have a look at the Paragraph (Image Embedded)}
(A) Geese reared by humans cannot be taught to respond to its own species.
(B) The hatching at an advanced stage is critical for imprinting.
(C) The capacity to recognize an adult of its own species is necessarily inherited.
(D) Rearing by humans does not alter the object of the behavioral routine.
Option A: “Geese reared by humans cannot be taught to respond to its own species” is correct. This is inferred from the 4th paragraph 2nd line: “When young geese are reared wholly by human beings it is towards humans that the young geese direct their behavioural routines”. This line clearly states that geese wholly reared by humans respond only towards humans. Also from the 2nd Paragraph 3rd line It is clear. Option B: “The hatching at an advanced stage is critical for imprinting” is false. 249
Hatching at an advanced Stage is not shown by Greylag Geese, it is shown by Godwits. (3rd Paragraph, 1st & 2nd Line: The young of Godwits hatch at an advanced stage of development and soon after hatching can recognize the adult bird.) (So the fact is not conclusive from Behavioural Pattern of Greylag Geese) Imprinting can be shown by Greylag Geese, which do not have a prolonged period of hatching, and imprinting totally depends on whatever creature happens to be present at the right moment in their development. Options C: “The capacity to recognise an adult of its own species is necessarily inherited” is false. According to the 2nd Paragraph, 2nd line: The capacities to recognise the right stimulus are not always inherited. Option D: “Rearing by Humans does not alter the object of the behavioural routine.” is false, as shown in 4th Paragraph 2nd & 3rd line: When young geese are reared wholly by human beings it is towards humans that the young geese direct their behavioural routines. Hence, answer should be A.
So Am I correct? 249
