    Question

    ‘Rosie’ the transgenic cow was developed

    to:
    A Increase wool production Correct Answer Incorrect Answer
    B Be resistant to foot-and-mouth disease Correct Answer Incorrect Answer
    C Improve meat quality Correct Answer Incorrect Answer
    D Produce human-like milk Correct Answer Incorrect Answer

    Solution

    Rosie was the first transgenic cow, developed in 1997, and she produced milk enriched with human protein α-lactalbumin. This milk was nutritionally more balanced and similar to human breast milk, making it beneficial for infants. Option (1) is incorrect because wool production is related to sheep, not cows. Option (2) is incorrect as Rosie was not developed for disease resistance. Option (3) is incorrect because her genetic modification was not aimed at improving meat quality. Thus, the correct answer is option (4).
