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:)

Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.

The runner in question wishes to complete a two-hour run while expending 4kcal or calories <u><em>per minute</em></u>, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.

Since <em><u>every gram of </u></em><em><u>protein </u></em><em><u>adds </u></em><em><u>4 calories </u></em><em><u>of energy to the meal</u></em>, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.
