Answer: Hadean Eon

The solar system was formed from cloud of dust and gasses. The solar nebula - from where sun was born about 4.5 billion years ago. It is believed that all the planets asteroids an were also formed then. The spinning matter collapsed under its own gravity rising the temperature and pressure and kicking in the nuclear fusion reaction forming the star - the Sun. The rest of the material formed the planets and asteroids. The geological era in which all these events happened to form the solar system is known as Hadean Eon.

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:)
