Answer:
Polycistronic mRNAs
Explanation:
Normally In Eukaryotic cells the messenger RNAs (mRNA) only contain the information to produce a protein, these mRNAs are known as monocistronic.
In Prokaryotes, the transcription system is usually polycistronic, this means that a mRNA have the information to encode two or more genes.
As an interesting example of the co-evolution of Eukaryotes, the mitochondrial genome has polycistronic genes.
I believe the punnet square is showing the genotypes of the F2 generation. If that is true, the answer would be 3 red : 1 white. This is because the four genotypes are RR, Rr, Rr, and rr. Out of those, 3 contain the dominant allele R that codes for red, while only one contains both recessive alleles that code for white. Hope this helps!
