Tuxumdonda urug'lanish jarayoni sodir bo'lganidan so'ng tuxum hujayra bachadon.,-■ nayiga o'tib, rivojlanishni davom ettiradi

(v15-106-34) Bulg'or qalampirida (R-C-) genlarining birgalikda bo'lishi mevasining qizil rangda bo'lishini ta'minlaydi, uiarning resessiv allellari esa mevasining yashil rangini yuzaga chiqaradi. Genotipda faqat birinchi juft allel gen dominant holda bo'lishi mevasining qo'ng'irligini, faqat ikkinchi juft alielining dominant holda bo'lishi esa mevasining sariq rangini namoyon etadi. Geterozigota sariq

va qo'ng'ir rangli o'simliklar chatishtirilganda avlodda olingan o'simliklarning genotipini aniqlang.
