Did you know that in guinea pigs, black color is dominant over white? This means that if a guinea pig carries one black allele and one white allele, it will still appear black. In genetics, we represent the different versions of a gene, called alleles, with letters. So, a heterozygous black guinea pig would have the genotype Bb, with B representing the black allele and b representing the white allele. On the other hand, a white guinea pig would be homozygous for the white color, so its genotype would be bb, where both alleles are white. Lastly, a homozygous black guinea pig would have the genotype BB, with both alleles being black. These genotypes determine the coloration of the guinea pigs, demonstrating how genetic traits are passed on and expressed.
