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.

What class of enzymes are involved in triggering events in the cell cycle?
ASHA 777 [7]
Kinases. Kinases add phosphate to molecules, and the modification can serve as a "switch" to turn events in the cell on or off. CDKs or cyclin dependent kinases regulate the cell cycle.

How does the sun heat Earth?
g100num [7]

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.
