Answer:
100% EE, 100% red eyes
Explanation:
For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.
The red eyes (E) is dominant while the white eyes (e) is recessive.
Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE
That is: EE × EE = EE, EE, EE, EE
Hence the genotype is 100% EE.
Also, the phenotype is 100 red eyes.
Answer:
Silencer
Explanation:
Silencers are the position and orientation free sequences that are present outside the protein-coding sequence of a gene. Silencers serve as a binding site for some transcriptional regulatory proteins that tend to inhibit gene expression. Binding of these "repressor" proteins to the silencers inhibits the gene expression.
The deletion of silencers from DNA would increase the rate of the gene expression as the inhibitory transcription regulatory proteins do not have binding sites to inhibit the gene expression. Therefore, the deletion of silencer sequences of the beta-globin gene would have caused the increased rate of its expression.
