(Worthy Insights) – In the shadow of ongoing war in the north, something rare emerged from a dairy farm tucked into the hills of the Galilee: a calf that was, against every genetic expectation, entirely red. No black hairs. No white hairs. Just the burnished copper coat that has made the parah adumah, the red heifer, one of the most sought-after animals in the history of the Jewish people.
Shai Givon, a specialist in artificial insemination at the company Piryon, discovered the calf. He had bred the dairy cow with semen from a Red Angus bull nine months earlier. This time, Givon wasn’t working alone. He is now part of the National Institute for Red Heifer Research, a body established to bring together halachic scholars, cattle specialists, and researchers under one roof as a national-scale project focused on the biblical commandment. Yehuda Ben Tzvi of the Temple Knowledge Seminary, one of the institute’s founding members, described the moment Givon called him with the news.
The genetics behind Temima’s coloring deepen the sense of the improbable. The mother was a dairy cow bred for black-and-white Holstein coloring. In standard cattle genetics, the black coat gene is dominant. When a black or dark-coated dairy cow is crossed with a Red Angus bull, the offspring will almost always express the dominant dark coloring of the mother’s breed. A fully red calf emerging from such a crossing is a genetic outlier, possible in theory, but vanishingly rare in practice. Givon himself, a professional who performs this procedure routinely across farms throughout the north, had never seen it happen. “I impregnated the parents with black Angus,” he told Ben Tzvi, “and the fact that it came out red is astonishing.” [ Source (Read More…) ]
