Everybody knows that positive charge is due to protons and negative charge is due to electrons, but what does the charge mean?
Why were negative and positive charges so designated?
Was it also a possibility to call the charge of an electron positive and the charge of a proton negative?

The answer is <span>100 percent purple
</span>
Let P be dominant allele for purple flowers and p recessive allele for white flowers. So purebred purple flower has two P alleles and its genotype is PP and purebread white flower has two p alleles and its genotype is pp. Since P is dominant over p, when found together like in heterozygous plants (Pp), the flowers will express dominant allele and will be purple.
So, a cross between <span>purebred purple flowering plants (PP) with purebred white flowering plants (pp) will have 100% of the offspring with genotype Pp and purple flower color.

Parents: PP x pp
Offspring: Pp Pp Pp Pp
