n tomato plants, tall vine (D) is dominant over dwarf vine (d) and round fruit (O) is dominant over oval-shaped fruit (o). Two tall, round-fruit shape plants (plants 1 and 2) are crossed with dwarf, oval-shape fruit plants. The results are as follows: i)  Why is there a difference in the proportionate number of plants in each phenotypic class of the offspring resulting from test crosses of plants 1 and 2?   (ii)  Calculate the recombination frequency between the genes D/d and O/o in tomatoes.  (iii)  Draw a chromosome map for these genes. (Use underscore (_) to draw the line for the map)

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.
