As in many animals, albino coat color is a recessive trait in guineapigs. Researchers removed the ovaries from an albino female guineapig and then transplanted ovaries from a true-breeding black guineapig. They then mated this albino female (with the transplanted ovaries) to an albino male. The albino female produced three offspring.What were their coat colors? Explain the results

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
