Answer:
R1 and R2 exhibit codominance.
Explanation:
In the given plant, pleiotropic locus regulates both berry color and berry size. The R1 allele gives red berries while the R0 allele is responsible for white berries. The heterozygote R0R1 also has red berries, which means that R1 is dominant over R0 for the color of berries. The R2 allele is responsible for the "small" size of berries in homozygous genotype.
The genotype R0R2 also has small berries, which means that R2 is also dominant to R0. However, the genotype R1R2 imparts red color and small size to berries. In the genotype R1R2, both the R1 (responsible for the red color of berries) and R2 (responsible for the small size of berries) alleles are expressed. This represents the fact that the R1 and R2 alleles are codominant and express themselves in heterozygous R1R2 genotype.
b. accelerate soil erosion by blocking in the land
c. prevent water runoff
d. decrease erosion losses by grazing animals
2)DNA synthesis involves conserving only part of each of the original strands in a DNA molecule.
3)The original DNA molecule is stored in the cell nucleus and serves as a template for creating copies containing two new strands.
4)DNA synthesis involves conserving one strand of a double helix of DNA and discarding the other.
