what is the difference between the closed conformation and open conformation of chromatin packing? biology
Oduvanchick [21]

The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.

  • The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
  • With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
  • All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
  • While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

In chickens, the dominant Cr allele produces chickens with extremely short legs (called creepers). When a male creeper is mated
Masteriza [31]

Answer:

The male creeper and the female creeper are both heterozygous for the creeping trait.

Explanation:

The creeping allele Cr is dominant. For any chicken to have the wild-type long leg attribute, the dominant allele must be absent in its genotype. This means that such an individual would have two recessive alleles, each from either parent.

Hence, in order for two parents to produce wild-type offspring at all, both of them would have to be heterozygous for the creeping trait.

Assuming that the alternate trait is represented by cr allele:

           Crcr    x    Crcr

    CrCr   Crcr   Crcr   crcr

<em>The two parents in the above cross are creepers but were able to produce wild-type offspring as a result of both parents being </em><em>heterozygous. </em>
