C. Dominant
The trait would be heterozygous which means one dominant allele and one recessive allele but the dominant allele always over powers the recessive allele
Metaphase is the correct answer
They ensured that balance in the ecosystem was maintained. They ensure that the genetic diversity and species is maintained. Sea otters applied natural selection pressures on the sea urchins population hence maintaining their level such that they will not overgraze on the kelps. Overgrazing would severely affect the sea urchin population and consequently severely affect the sea otters population too.
For this you would use a punnet square (ill try my best to show it while typing)
heterozygous means different, so with the purple flower youd get the gene shown as Pp and put it into the punnet square
P p
P PP Pp
p Pp pp
given the possibilities in the punnet square the genes with at least one P is going to be purple and the genes with 2 "p"s are going to be white
so you would have
25% Dominate Homozygous Purple
50% Dominate Heterozygous Purple
25% Recessive Homozygous White
