Here are the main points that make difference between facilitated diffusion and active transport are : facilitated diffusion goes from high to low - deffuse in a selectively permeable membrane and does not demand energy. What about <span>active transport - it uses energy and moves against gradient- low to high. Hope it will help!</span>
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.
