Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces color
Pie

Answer:

The genes are linked, and the arrangement is coupled (one homolog has both dominant alleles; the other homolog has both recessive alleles).

RY / ry

Explanation:

R_= colored aleurone

rr= colorless aeurone

Y_= green plant

yy= yellow plant

They do a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits (yr/yr) the following F1 is obtained:

  • 88 Colored, green (RY/ry)
  • 92 colorless, yellow (ry/ry)
  • 8 colorless, green (rY/ry)
  • 12 colored, yellow (Ry/ry)

If the genes assorted independently, all of the possible offspring phenotypes would appear in the same frequency. However, they obtained 2 phenotypes much more abundant that the other two. Since recombination is a rare event during crossing over, when two genes are linked the recombinant gametes are produced less frequently than the parentals.

We can propose that the phenotypes Colored, green (RY) and colorless yellow (ry) are the parental gametes, and the unknown plant has the arrangement RY/ry, with both genes linked.

Construct incomplete dominance vs codominance
Firlakuza [10]

Answer:

Codominance is when both alleles in the genotype are seen in the phenotype, like a flower that is half blue and half red. Incomplete dominance is a mixture of the alleles, like for example, a mixture of blue and red flower, a purple flower.
