This state is characteristic for recessive traits. For an individual to express a recessive trait, it must have two recessive alleles (one of two or more alternative forms of a gene) of the responsible gene. But, if it has one recessive allele and one dominant allele, it will not have the trait, but he will be called a carrier. So, it seems like the trait "disappeared" but still it is "carried" in the genome. However, if its offspring has two recessive alleles and express the trait, it will <span>seem </span>like the trait "reappeared".

How can nuclei accommodateall of our genetic material<br> (3,000,000,000 base pairs)?
mr_godi [17]

Answer:

By forming chromatin and in the condensed form of chromosomes

Explanation:

The human genome contains around 3 billion base pairs which are located in the nucleus of all cells. In order to accomodate such large genomic information, DNA is maximally supercoiled during mitosis and meiosis processes to form condensed structures called chromosomes. Humans have 23 pairs of chromosomes per somatic cell. The supercoiling process is assisted by a family of proteins called histones, which interact with DNA and regulate its conformation. The complex between DNA and histones within the nucleus is called chromatin. When chromatin is supercoiled it form chromosomes (in eukaryotic cells).
