In the Mexican hairless breed of dog, the lack of hair corresponds to the H/h genotype. Normal dogs (with hair) are homozygous h/h for the recessive allele. Puppies H/H are stillborn and they display severe muzzle abnormalities and a lack of inner ear. a) Which crosses can give hairless dogs at the next generation ? b) Which one gives the highest frequency of hairless dog for a breeder (only viable animals will be taken into account)?

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.
