Gene regulation in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription. Any step of gene expression may be modulated, from the DNA-RNA transcription step to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, the most extensively utilised point is Transcription Initiation: Chromatin domains.

In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptors on liver
JulsSmile [24]

Answer:

The correct answer is - incomplete dominance.

Explanation:

A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.

In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.

Thus, it is the case of incomplete dominance.

sertanlavr [38]
As the individual body size of an organism increases, the population density for this organism in a given habitat tends to decrease.

  <span>It has been shown that an inverse relationship between the size of an animal and its local abundance exist. Animals with larger body size have higher energetic requirements, resource exploitation, and susceptibility to predation and thus the competition is bigger. Yet, the density–body size relation depends on the physical complexity of the habitat and population of a species.</span>
