A gene that affects hair length in dogs has two alleles. The allele for short hair (L) is dominant to the allele for long hair (1). A cross of two short-haired dogs produces six short-haired and two long-haired offspring. Which of the following best explains how the long-hair phenotype can appear in the offspring of two short-haired dogs? A. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring. B. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction. C. Only recessive alleles are inherited from homozygous parents. D. Dominant alleles grow weaker as they are passed from parents to offspring.
