A student analyzed ears of corn that demonstrated two traits in the F2 kernels, purple or white colors and smooth or wrinkled sh
Sunny_sXe [5.5K]
The answer is purple and smooth.

It is known that the in dihybrid cross (a cross between two different traits), the phenotypic ratio between the offspring of two heterozygous parents in the F2 generation is 9:3:3:1.

<span>purple and smooth = 75                (</span><span>≈ 9 </span><span>· 8)</span>

<span>white and smooth = 28                  (</span><span>≈ 3 </span><span>· 8)</span>

<span>purple and wrinkled = 24               (= 3 </span><span>· 8)</span>

<span>white and wrinkled = 8                   (= 1 </span><span>· 8)</span>

<span>
</span>

So, the ratio between the offspring is close to 9:3:3:1 in F2 generation.


This means, that the only heterozygotes are present in the F1 generation, and they must be purple and smooth.

djverab [1.8K]

Menjawab:

a) 250N

b) 250Watt

Penjelasan:

a) Upaya yang dilakukan beny untuk mendorong gerobak tersebut setara dengan gaya yang diterapkan untuk mendorong beban. Oleh karena itu, Effort beny yang digunakan setara dengan 250N

b) Daya = Pekerjaan selesai / Waktu

Karena usaha yang dilakukan = Gaya × jarak

Daya = Gaya × jarak / waktu

Diberikan

Angkatan = 250N

Jarak = 50m

Waktu = 50 detik

Yg dibutuhkan

Power Beny melakukannya untuk mendorong keranjang belanjaan.

Daya = 250 × 50/50

Daya = 12500/50

Daya = 250Watt

Oleh karena itu, Benny menggunakan tenaga 250 watt untuk mendorong kereta belanja tersebut
