Chơng II - Tính quy luật của hiện tợng di truyền
Bài 8: Quy luật menđen: quy luật phân li
I- Mục tiêu:
1. Kiến thức:
Sau khi học xong bài này học sinh phải
- Nêu đợc thí nghiệm và cách giải thích kết quả thí nghiệm của Menden. Nêu đợc nội dung
của quy luật phân li.
- Trình bày đợc cơ sở tế bào học của quy luật phân li.
2. Kỹ năng & thái độ:
- Rèn luyện kỹ năng quan sát và phân tích kênh hình để từ đó thu nhận thông tin.
- Có ý thức vận dụng kiến thức về quy luật phân li vào thực tiễn sản xuất.
II- Chuẩn bị:
1. GV:
- Phim( ảnh động) về lai một tính và cơ sở tế bào học của quy luật phân li.
- Phiếu học tập.
2. HS:
- Xem lại bài 2, 3 SH 9.
- Tấm bản trong( hoặc giấy rôki), bút phớt.
