Answer: the functions of the skeleton. Structure, protection (ribs), allow movement, chemical/physiological: stores calcium and the tissues are made up of the same material

Answer:
C) Through genomic imprinting, methylation regulates expression of the paternal copy of the gene in the brain.
Explanation:
The pattern of gene expression wherein either paternal or maternal gene is expressed in specific cells while the other one is prevented from expression is known as genomic imprinting.
In the given example, the maternal copy of the gene on chromosome 15 is expressed in brain cells while its paternal copy is not expressed in these cells. Hence, the pattern of expression of this gene is regulated through genome imprinting. One of the mechanism is methylation of cytidine residues of CpG islands of the DNA that are more frequently present within promoters of the genes.
When the cytidine residues of these sequences are methylated into 5-methylcytidine, the transcription factors do not bind to these promoters preventing the expression of these genes.
Hence, methylation of cytidine residue in CpG islands of the promoters of the gene present on chromosome 15 could have silenced its expression in brain cells.

Answer:
The hardy-Weinberg OR Hardy- Weinberg equilibrium is the model that describes that the frequency of genotype and allele frequency remain constant if there is no evolutionary influences, generation to generation.
According to this model:
p+ q = 1
p² + q²+ 2pq= 1
Thus, the given case does not follow the Hardy Weinberg principle which means there is some type of influence of the evolutionary change is occurred in the particular population.
