An apple tree can reproduce both sexually and asexually. A botanist crosses a red-rooted apple tree (RR) with a yellow-rooted apple tree (rr). The plants produced five red fruits and five yellow fruits. The botanist cuts pieces from the rooted apple tree's branches, places them in soil, and waits for them to grow new roots, leaves, and fruits. The botanist learns that the red-root apple plant reproduces asexually, and the fruits of its offspring are always red. Identify the combinations of genotypes that would be produced in this plant. Where does this represent sexual or asexual reproduction?
a) RR and rr; sexual reproduction
b) RR and RR; asexual reproduction
c) rr and rr; asexual reproduction
d) RR and Rr; sexual reproduction
