Homozygous on both signs Dark shaggy guinea pigs crossed with a white smooth pork.

Homozygous on both signs Dark shaggy guinea pigs crossed with a white smooth pork. Determine the genotypes and phenotypes of the first and second generations, if the dark and shaggy fur dominates white and smooth.

Let a – dark color, then a – white;

B – shaggy wool, B is smooth.
