In mallard ducks, Anas platyrhynchos, plumage is under control of a single gene with three alleles: M, which codes for wild-type mallard plumage; MR, which codes for restricted plumage; and MD, which codes for dominant plumage. all three types of plumage breed true.  Deduce the dominance hierarcy of the three alleles based on the following crosses Cross                                                            Offspring a. Dusky x Mallard                           1/2 Dusky : 1/2 Mallard b. Dusky x Restricted                        1/2 Dusky : 1/2 Restricted c. Mallard x Mallard                           3/4 Mallard : 1/4 Dusky d. Mallard x Restricted                       1/2 Restricted : 1/4 Mallard : 1/4 Dusky

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.
