Question

When two plants, both y’all, were crossed, they produced some offspring that were dwarves. Assuming that the height of the plant is controlled by a single gene and the allele for the tall plant is dominant, what is t he genotype of the parents

Answer 1

Answer:

Both parents have a genotype of Tt

Explanation:

Let's say the genotype for tall is T and the genotype of short is t

When the plants are crossed, it looks a little like this:

                                                                                         I  T    I     t    I

                                                                                  I   T  I  TT  I   Tt   I

                                                                                  I   t   I   Tt  I   tt    I

                            The lower case tt represents the dwarf plants

Hope this helps :)
