In a certain breed of dog, white spots (w) in their fur is recessive to a solid color coat of fur (W). What would the genotype(s) of a dog with no spots be?

either WW (homozygous dominant) or Ww(homozygous dominant)

Explanation:

If Solid coat is dominant (W) then there are two options. It’s dominant so any genotype with (W) will have the phenotype of Solid coat, or no spots.

the question isn't complete here so i can't right an answer '_'

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
