Question

An apple tree can reproduce both sexually and asexually. A botanist crosses a red-fruited apple tree (Rr) with a yellow-fruited apple tree (rr). Of the ten plants produced, five grow red fruit and five grow yellow fruit.

The botanist cuts pieces from the red-fruited apple tree’s branches, places them in soil, and waits for them to grow new roots, leaves, and fruits. The botanist learns that when this red-fruited apple plant reproduces asexually, the fruits of its offspring are always red.

Identify the four gene combinations (genotypes) that would be produced in this Punnet square. Does this represent sexual or asexual reproduction?
