Lobaratoriya mashg'uloti - 3
Mavzu: Organizimlarda irsiyat va o'zgaruvchanlikni o'rganish
Maqsad: hayotning molekula va hujayra darajasidagi umumbiologik qonuniyatlarga doir masalalar yechish orqali biologik obyektlarda boradigan jarayonlarni kuzatish, tajribalar o‘tkazish va xulosa qilish kompetensiyasini shakllantirish.
Jihоzlаr: hayotning molekula va hujayra darajasidagi umumbiologik qonuniyat larni aks ettiruvchi rangli rasmlar, slaydlar

Ishni bajarish tartibi:

Partaga 10tadan yashil bronza qon`g`izi,uning rasmlari tarqatiladi.
1.Individlarni tashqi ko`rinishini o`rganish, o`zaro taqqoslash
2.Ulardagi irsiyatni –o`xshash xususiyatni aniqlash
3.Ulardagi individual o`zgaruvchanlikni aniqlash
4.Kuzatuvlar asosida jadvalni to`ldirish
