if black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of?
If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of?
Answer:
The scenario described with black and white true-breeding mice resulting in all gray offspring suggests incomplete dominance as the likely inheritance pattern. In incomplete dominance, neither allele is completely dominant over the other, and the combination of the two alleles results in an intermediate phenotype. In this case, the black and white alleles mix to produce the gray coat color in the offspring. This pattern is distinct from complete dominance where one allele is fully dominant over the other, and from codominance where both alleles are fully expressed simultaneously. Incomplete dominance leads to a blending of traits from the two parental phenotypes, giving rise to the observed gray coat color in this scenario.
