8. A budding horticulturist at the U of S is developing a new species of strawberry, Straw berrylis. They are particularly interested in the inheritance of genes that influence the size (B) and colour (E) of the strawberry fruit. The horticulturist begins their experiments by crossing a line of Straw berrylis that produces large berries with a line that produces small berries. The offspring from this cross (the F,) all had small berries. a. Which phenotype is dominant? b. How do you know? Give the genotype of each of the following: Parent 2 F, Parent 1
