a certain species of plant, a dihybrid (round, pink seeds) is mated with a test-cross strain (wrinkled, white seeds).  The following progeny are obtained: round, pink – 440 round, white – 76 wrinkled, pink - 84 wrinkled, white - 400   What is the distance (in map units) between the two genes in question? Your answer should be a single whole number between 0 and 50.  Choose 50 if you think the genes are not linked.

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.
