Answer:

Theory

Explanation:

A scientific theory is what best fits your description. A scientific theory basically explains aspects of the natural world. However, scientific theories are not just ideas, it is based on collaborative works that tests the idea through the scientific method. Theories are verified through repeated testing.

Scientific hypotheses can eventually become a scientific theory when results have been verified through repeated testing.

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.

boyakko [2]
Yes. the nucleotides are A, T, G, and C. A and T pair up and G and C pair up. For instance, if your known strand is AGTCAG then the second strand would have to be TCAGTC. Also, if there is a U in the strand, it takes the place of T. so the original strand would be AGTCAG and the unknown would have to be UCAGUC.
