Question

If the green allele is designated as G, and the aurea allele is designated as GA , assign genotypes to the phenotypes listed. Drag the pheontype at the left to the appropriate blank on the right.

Answer 1

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
