In a species of beetles, individuals may be red, black, white or tan. Colour is controlled by a single gene with multiple alleles in a dominance series. Red (R) is dominant to black (Rb), black is dominant to white (Rw) and white is dominant to tan (r) (R > Rb > Rw > r). Colour variation in this species is a female sex-limited trait. Males carry the colour genes but are always phenotypically tan regardless of their genotype. What are the genotypes of the parents of the following cross?     white female × tan male produce 13 red females: 6 white females: 5 tan females: 19 tan males

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.
