In a breed of mice fur coat color is determined by two genes. For coat color BB results in black, BT results in black with tan spots and TT results in tan. However, to have coat color there must be at least one dominant allele of gene A where aa is white (no color). (a)For each trait, give the type of inheritance demonstrated. Color of fur and if there is color.   A (1) tan mouse heterozygous for coat color is crossed with a (2) Black and tan spotted mouse that is homozygous for color   (b) What is the genotype of the two parents involved in the cross?   (c) When crossed, what is the chance of getting a tan mouse? Show your work (you may either use a Punnett square or Fork method).

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.
