In guinea pigs, black coat color is dominant over white coat color. The
of a mating between two heterozygous black guinea pigs would probably show a
phenotype ratio of

Respuesta :

If they are both heterozygous black guinea pigs they both carry the allele for white fur. Therefore, the phenotype ratio would be 3:1 (75% offspring will be black furred, and a 25% it will be white furred). You can figure this out by using a punnet square too.

The result of mating between two heterozygous black guinea pigs will show a phenotype ratio of 3:1 black to white.

Assuming the allele for black is B and that of white is b.

Crossing 2 heterozygous individuals:

                             Bb     x     Bb

                            BB   Bb   Bb   bb

Offspring

  • 1/4 BB - black
  • 1/2 Bb - black
  • 1/4 bb - white

Thus, 3/4 or 75% of the offspring will be black while 1/4 or 25% will be white. These culminate in a phenotypic ratio of 3:1.
