Answer:

relaxed packaging of the chromatin and increased transcription.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.

Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

In some bunnies, the gene for fur color is controlled by condominance. The allele for gray color is G and the allele white color
Inessa05 [86]

Answer:

Genotype gray bunnies: GG

Genotype white bunnies: WW

Genotype gray and white bunnies: GW

Explanation:

In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.
