In the chinchilla, albino coat color is a recessive trait. Researchers transplanted ovaries from an albino female chinchilla into a true-breeding black chinchilla. They then mated this black chinchilla female (with the transplanted ovaries) to an albino male. The albino female produced three offspring. What were their coat colors? Explain the results.
The three offspring would all have black coats. This is because the female chinchilla who gave birth to them had black fur and therefore must have had at least one dominant allele for black coat color. This dominant allele would have been present in all of her eggs, despite the fact that she was born from an albino female's ovaries. When these eggs were fertilized by the albino male, each offspring received one dominant allele for black from the mother and one recessive allele for albino from the father (since the albino male can only contribute a recessive allele). Therefore, all three offspring would have black fur, despite their grandmother's albino coat color.
