in the mutated snapdragon plants, the green leaves started becoming yellow. this conditioned plant is known as, aurea, which has less chlorophyll than green plants.

Crosses had done between various combinations of green and aurea plants and the result was- green x green = all green

aurea x aurea = 2/3 aurea, 1/3 green

green x aurea = 1/2 green, 1/2 aurea

here, the green allele is G, and the aurea allele is GA,

according to the question, in the cross of plants,

the green plants produced all green but some of the crosses of aurea phenotype also gave the green phenotype.

so it can be concluded that the green phenotype (the wild type) came from the recessive allele. No instances of incomplete dominance or codominance were shown.

Thus, the following genotypes would have their phenotypes, as follows:

GG - green

GAGA - aurea

GGA - aurea

If the top level consumers were eliminated from a food web would the populations in the levels below them increase without bound

Vera_Pavlovna [14]

Answer:

That isn't true

Explanation:

That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.

Hop this Helps!
