bapak/ibu, tolong jelaskan tentang persilangan monohibrid dominan, intermediat dan dihibrid dominan, intermediat (yang meliputi gamet, F1,F2 dan perbandingan fenotipe dan genotipenya. terima kasih...
Persilangan monohibrit dominan, Fenotif F1 sama dengan fenotif induk dominan, perbandingan fenotif 3:1. perbandingan genotif 1 :2 :1.
Persilangan monohibrit intermediat, fenotif F1 tidak sama dengan fenotif kedua induknya tetapi merupakan sifat antara keduanya. perbandingan fenotif dan genotif sama yaitu 1:2:1.
Persilangan dihibrid dominan, rasio fenotif 9:3:3:1, Rasio genotif 1:2:1:2:4:2:1:2:1
pak/bu,tolong jelaskan apa yang dimaksud dengan istilah genotipe,fenotipe,resesif,dan dominan beserta contohnya. terima kasih banyak.
genotif, sifat dari gen yang tak dapat diindera sehingga ditulis dalam bentuk lambang berupa huruf, huruf besar menunjukkan sifat dominan, yaitu sifat yang pengaruhnya menutupi sifat resesif. Resesif ditulis dalam huruf kecil, sifat resesif sifat yang pengaruhnya tertutup oleh sifat dominan.
Fenotif sifat yang dapat diindera, sifat fenotif merupakan interaksi antara sifat genotif dengan lingkungan. Contoh fenotif; rambut hitam, rambut coklat, hidung mancung, kucing berbulu putih dll. Contoh genotif HH (sifat dominan) untuk bunga warna merah, genotif hh (sifat resesif) untuk bunga warna putih, maka gen Hh akan menunjukkan warna merah bila gen H bersifat dominan penuh, sebab sifat H akan menutup pengaruh dari h.
hasil oogenesis pada angiospermae apa??
Oogenesis merupakan proses pembentukan sel telur. Inti dalam bakal biji mengalami pembelahan meiosis menjadi 4 buah sel baru yang tiga diantaranya mengalami degradasi (mati). Yang hidup mengalami pembelahan mitosis tiga kali sehingga terbentuk 8 buah sel dan membentuk konfigurasi tertentu. Tiga sel paling ujung disebut antipoda (mengalami degradasi ), dua sel di tengah membentuk inti polar (disebut inti kandung lembaga sekunder ), tiga sel lainnya terletak di depan mikrofil; sel di tengah disebut inti sel telur dan diapit oleh sinergid (keduanya akan mengalami degradasi)
RR.RETNO YOSIANI T SARI, S.Pd.
belalang jantan berbadan hijau sayap panjang (HhPp) dikawinkan dengan belalang betina berbadan cokelat sayap pendek (hhpp). pada gen H dan P maupun gen h dan p terjadi pautan. dari hasil perkawinan tersebut diperoleh fenotipe keturunan sbb. hijau sayap panjang:hijau sayap pendek:cokelat sayap panjang:cokelat sayap pendek dengan hasil 530:450:782:310. berdasarkan kasus tersebut dapat disimpulkan bahwa selama pembentukan gamet terjadi pindah silang dengan nilai pindah sil;aang sebesar??
Nilai pindah silang
= (Jumlah tipe rekomendasi/jumlah seluruh individu) x 100%
= (1232 /2072) x 100 %
= 59,45 %
dari persilangan ayam berjengger walnut (RrPp) engan ayam berjengger pea (rrPp), kemungkinan akan diperoleh keturunan berjengger walnut:rose:pea:single dengan perbandingan??
Perhatikan skema penyilangan berikut:
Walnut X Pea
RrPp X rrPp
rP rp
RP RrPP(walnut) RrPp(walnut)
Rp RrPp(walnut) Rrpp(rose)
rP rrPP(pea) rrPp(pea)
rp rrPp(pea) rrpp(single)
Rasio fenotip:
walnut : pea : rose : single = 3 : 3 : 1 : 1
dari persilangan lalat buah abu-abu sayap panjang heterozigot dengan lalat buah hitam sayap pendek, didapatkan keturunan 400 ekor, di antara turunan itu ditemukan lalat abu-abu sayap pendek 30 ekor dan lalat hitap sayap panjang 20 ekor. persentase gen yang mengalami pindah silang??
Prosentase pindah silang
Lalat abu - abu sayap pendek =
(30/400) X 100% = 7,5 %
Lalat hitam panjang =
(20/400) X 100 % = 5 %

tolong contoh report text tentang bali 250 kata, sekarang!
There were so many places to see in Bali that my friend decided to join the tours to see as much as possible. My friend stayed in Kuta on arrival. He spent the first three days swimming and surfing on Kuta beach. He visited some tour agents and selected two tours. The first one was to Singaraja, the second was to Ubud.
On the day of the tour, he was ready. My friend and his group drove on through mountains. Singaraja is a city of about 90 thousands people. It is a busy but quiet town. The street are lined with trees and there are many old Dutch houses. Then they returned very late in the evening to Kuta.
The second tour to Ubud was a very different tour. It was not to see the scenery but to see the art and the craft of the island. The first stop was at Batubulan, a center of stone sculpture. There my friend watched young boys were carving away at big blocks of stone. The next stop was Celuk, a center for silversmiths and goldensmiths. After that he stopped a little while for lunch at Sukawati and on to mass. Mass is a tourist center
My friend ten-day-stay ended very quickly beside his two tour, all his day was spent on the beach. He went sailing or surfboarding every day. He was quiet satisfied.
