An allele for coat color in mice, Y, produces a yellow coat color when present. The phenotypes of the F1 generation are shown. A cross between a Non-yellow mouse and yellow mouse produces half yellow and half non-yellow progeny (offsprings). Non-yellow happens to be white in this example, but it does not need to be; it can be black, grey, or some other mouse color. Identify the genotype of the "Dead" phenotype. Describe the rationale behind your genotypic selection. * Pgeneration Yellow Non-yellow

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.
