A plant can have green(G) or yellow(g) leaves. It can also have a long(K) or short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype ggKk. What possible gametes can the plant produce?
This plant can produce only the g allele for leaf color, but can produce the K or k allele for stem length. The possible combinations are: gK (green leaves, long stem) and gk (green leaves, short stem)
