If either color allele is present as a homozygous recessive, c/c or r/r, the kernel will be white. Both alleles must be present as homozygous or heterozygous dominants for the kernel to be colored. Both parents are homozygous pr/pr, which gives a red as opposed to a purple kernel.
The size of planet Pluto is 1410 miles. But Pluto is now no longer a planet o body knows what actually happened at the precise time.
Pluto is still an interesting member of the solar system, however - its orbit is actually very eccentric and takes Pluto 4,400,000,000 - 7,400,000,000 km (30 - 49 AU) from the Sun. Pluto's orbit is also inclined with respect to the planets and doesn't fall within the same plane.
