In radishes, the gene that controls color exhibits incomplete dominance. Pure-breeding red radishes crossed with pure-breeding white radishes make purple radishes. What are the genotypic and phenotypic ratios when you cross a purple radish with a white radish?

Genotype Ratio = 1 RW: 1 WW

Phenotype = 1 Purple: 1 White

Explanation:

The gene for the color of radishes exhibits incomplete dominance and the heterozygous genotype gives purple color to radishes. The genotype of the heterozygous parent plant with purple radishes would be "RW." A cross between a purple radish (RW) and a white radish (WW) would give progeny in the following ratio.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
