In some breeds of chickens, there are alleles for black color and white color. Neither of these alleles is dominant over the other. When a chicken of one of these breeds has both of these alleles, its color is black-and-white spotted (which is also called erminette). If a spotted chicken is bred with a black chicken, the phenotypes of the offspring will occur in what ratio? (Hint: Construct a Punnett square to help you answer this question.) A 1:2:1 ratio of black, spotted, and white A 1:1 ratio of spotted and white A 1:1 ratio of black and spotted A 1:3 ratio of white and black

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.
