Imagine that you went to the pet store and bought two black guinea pigs that are known to be heterozygoues (Bb). You also kno whtat black fur (BB) is dominant over white fur (bb), and a that a lethal recessive allele is located only one cM away from the recessive (b) allele. You decide to start raising your own guinea pigs, but after mating these animals several times, you discover they only produce only black progeny.  a) How would you explain this result b) what is the probability of your two black guinea pigs producing white offspring?  c) If an average mating produces 10 offspring, how many matings would it take to produce a white offspring?

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.
