A capsule stain is described as a negative stain because the capsule itself __________. does not take up stain has a negative ch
KonstantinChe [14]

Answer:

Does not take up the stain.

Explanation:

Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.

One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.

Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.

A heterozygous tall pea plant is allowed to self-fertilize. The resulting F1 progeny are 25% homozygous tall, 50% heterozygous t
maks197457 [2]

Answer:

25% heterozygous tall

Explanation:

If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.

The first one for homozygous tall, then we have 100% AA.

The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.

The last one would be for dwarf, and we'll have 100%aa.

Adding all of them, we'll have

AA = 100 + 25 + 25 = 150%

Aa =  50+50 = 100%

aa = 100 + 25 + 25 = 150%

as we had 4 crosses, so dividing the total percentages by 4, we'll have,

AA = 37.5%

Aa = 25%

aa = 37.5%

:. The percentage of heterozygous tall would be 25%.

Hope it helps:)
