Question

Assertion (A): The milk produced by transgenic cow ‘Rosie’ was nutritionally more balanced product for human babies than natural cow milk.

Reason (R): It was human protein enriched milk containing human alpha lactaglobulin.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation for Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).

Explanation:

Rosie was the first transgenic cow to produce milk enriched with the human protein alpha‑lactalbumin (reported at ~2.4 g/L), a milestone achieved in 1997.
Alpha‑lactalbumin is a dominant whey protein in human milk, and increasing its proportion in bovine milk makes the protein composition closer to human milk, so Rosie’s milk was considered a more nutritionally balanced product for human infants than ordinary cow milk.
