A certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. An RR grasshopper has red stri
pes, an YY grasshopper has yellow stripes, and an RY grasshopper has red and yellow stripes. A grasshopper with red stripes mates with a grasshopper with yellow stripes. What ratio would you expect to see in the phenotypes of their offspring?
All of the offspring will have RY (Red and yellow stripes). If you set up a punnet square and solve, you will see that all four offspring have RY genotype, therefore their phenotype is red and yellow stripes
Hoy en día, podemos incorporar nuevos genes de una especie en una especie completamente no relacionada a través de la ingeniería genética, optimizando el rendimiento agrícola.
<em>Q1. Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur normally. Consider how the absence of crossing over would affect the outcome of meiosis.</em>
