A farmer has two homozygous varieties of tomatoes. One variety, calledLittle Pete, has fruits that average only 2 cm in diameter. The other variety, Big Boy, has fruits that average a whopping 14 cm in diameter. The farmer crosses Little Pete and Big Boy; he then intercrosses the F1 to produce F2 progeny. He grows 2000 F2 tomato plants and doesn’t find any F2 offspring that produce fruits as small as Little Pete or as large as Big Boy. If we assume that the difference between these varieties in fruit size is produced by genes with equal and additive effects, what can weconclude about the minimum number of loci with pairs of alleles determining the difference in fruit size between the two varieties?

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.
