In certain rats black fur is the dominant trait while white fur is the recessive trait. If two heterozygous rats are mated their offspring would be expected to have?

If two heterozygous rats (Bb) are mated, where B represents the dominant black fur and b represents the recessive white fur, their offspring would follow a typical Mendelian inheritance pattern. The expected genotypic ratio of the offspring would be 1 BB (homozygous black) : 2 Bb (heterozygous black) : 1 bb (homozygous white). Consequently, about 75% of the offspring would have black fur and 25% would have white fur.
