मानव में बच्चे का लिंग निर्धारण कैसे होता है?
Answered by admin @
उत्तर :
मानव में बच्चे का लिंग निर्धारण इस बात पर निर्भर करता है कि उन्हें पिता से कौन सा लिंग गुणसूत्र प्राप्त हुआ है। मानव में 46 से गुणसूत्र होते हैं। इनमें से 44 गुणसूत्रों के 22 समजात जोड़े होते हैं जिन्हें ऑटोसोम्स कहते हैं। शेष एक जोड़ा लिंग गुणसूत्र कहलाते हैं । पुरूष तथा स्त्री में लिंग गुणसूत्रों का यह जोड़ा एक दूसरे से अलग होता है। जिस बच्चे में अपने पिता से X गुणसूत्र वंशानुगत हुआ है वह लड़की एवं जिसे पिता से Y गुणसूत्र वंशानुगत हुआ है वह लड़का होता है।
पुरूष में 22 जोड़े + XY = 46 गुणसूत्र
स्त्री में 22 जोड़े + XX = 46 गुणसूत्र
आशा है कि यह उत्तर आपकी मदद करेगा।
