Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

Explanation:

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

= 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

= 75% green, 25% albino

Answer:

Gas from Earth's core came to the surface through volcanoes.

Recent hypotheses about the origin of organic molecules suggest that these molecules may have formed in hydrothermal vents deep in the oceans, where hot gases and elements emerge from cracks in Earth's crust.
