In the heterozygous state (w +/w), a variegated eye is produced, with white and red patches. The following statements are true in relation to this experiment:
b. When heterochromatin spreading does not reach the new location of the w + allele, the gene will be transcribed, producing red eye patches.
c. When heterochromatin spreading encompasses the new location of w + allele, the gene is transcribed, producing white eye patches.
d. Even though eye color phenotypic variegation exists within the eye, all cells have the same genotype.
Explanation:
Heterochromatin in droshophila has genes which gets expressed by position effect variegation. In some normally active cells genes are silenced in some due to transposition of genes which causes change or variegating in phenotype.
This change is due to change in position of the gene in the genome and chromosome but no change in gene.
The variegation in drsophilla melanogaster shows that white gene was not damaged.
The rearrrangement of gene takees place at pericentric heterochromatin.
Heterochromatin is required for maintaining genome integrity and regulating gene expression. When spread in neighboring region it can inactivate the genes present there.
The genes taking part in variegation remains same hence no change in genotype.
The Cerebellum(the back of the brain) coordinates voluntary muscle movements and maintains posture, balance and equilibrium.
Answer: It is basically when DNA is added to a gene to enhance the way a person performs in athletics.
Explanation:
An average person could be conscious or are able to live without eating for about thirty days. Though what's more important is that the person is having water because water is very vital and essential to the body for it is the most abundant component that could be found in a person's body. Without it, the person without eating and has no water intake could only take him or her three days.
Answer:
The more basic characteristic for classifying organisms is the kind of cells they are made of because different organisms may share same habitat but may have entirely different form and structure.
