Genome refers to the total DNA present in the nucleus of the cell, i.e. nuclear DNA of a eukaryotic cell. In prokaryotic cells, the nucleus is... View Article
The haploid human genome constitutes around 3.1 billion base pairs of DNA. Around 99.9% of nucleotides are the same in all people. The human... View Article
Genetics deals with the study of inheritance, structure of DNA, genes, chromosomes and various related processes. Application of genetics... View Article
99.9 percent of nucleotides are the same in all the people. 0.1 percent of the genome accounts for variation and unique characteristics of each... View Article
The human genome consists of 3.1 billion nucleotides pairs in a haploid set. So most of the cells have 6.2 billion base pairs. Further reading:... View Article
Yes, genetic drift can result in the extinction of population, loss of alleles, i.e. loss of genetic diversity. Genetic drift is more prominent... View Article
The main reasons for variations in a population are mutation and genetic recombination during sexual reproduction. Further reading: Organic... View Article
Genetic drift is the change in gene frequencies of a population due to chance events. Its effect is more prominent in small populations. It may... View Article
Natural selection work on variation existing in a population. Variation exists in a population due to mutation and recombination during sexual... View Article
