In common laboratory mice, there are three recessive genes known as: h, hotfoot pattern and o, obese and wa, waved fur. A trihybrid parent of unknown genotype is test crossed, producing the following offspring. Hotfoot, obese, waved -357 Hotfoot, obese -74 Waved --66 Obese- -79 Wild-type -343 Hot food, waved -61 Obese, waved -11 Hotfoot- (a) What is the genotype of the unknown parent? Be specific with your allelic arrangement. (b) Determine the chromosome map (HINT: be careful with your groupings, be sure to double check your SCOS!) (c) Is there any crossover interference going on? Determine the coefficient of coincidence and interference values.

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.
