The human organism contains threadlike, gene-bearing chromosomes, twenty three pairs of them. These chromosomes contain the complete heredity, including characteristics such as the color of the eyes, the hair and skin. One specific pair of chromosomes determines the sex or gender of the individual.
Inherited Traits, Mutations, DNA & Genes
Ever wonder where you got your blue eyes or red hair? What DNA traits dictate freckles or dimples? Read all about your inherited traits, DNA and genes as well as fascinating articles on mutations and mutated chromosomes.
Chromosomal disorders are caused by an absence, excess or abnormal arrangement of 1 or more chromosomes. The defects are there from birth; while some are harmless many cause severe disorders. This article is a brief look at some of the conditions caused by changes in their structure.
Does cheating have a genetic basis? Is it possible that if you have a specific variant of a gene (a monogamy gene) you may be more prone to cheating and be less faithful in your relationships? A new study has some startling answers.
There has been a major advance in our understanding of the genetic basis of one of the most common forms of leukaemia. For the first time scientists have showed a genetic susceptibility to developing Chronic lymphocytic leukaemia or CLL, research which could one day benefit people with leukaemia.
It is a sad fact of life that every year millions of children are born with birth defects that are caused solely or partially by genetic defects. This article looks at where they occur in the world and what can be done about them.
Evolution is easy to see when you look back over the earth’s history. But evolution is not full of large, significant events: instead it is an enormous collection of tiny genetic changes which occurred over thousands of millions of years.
Mitochondrial Eve, an ancient matrilineal ancestor, is perhaps the more famous of the pair, but her male counterpart, Y-chromosomal Adam, is just as interesting a figure in human evolution.
Genetic disorders are diseases or conditions that are caused by abnormalities in genes or chromosomes. Some are known at birth, whilst others make an appearance later in life.
Bioinformatics is being used in many realms of the scientific world, and is also allowing extensive work to be done in the medical community as well.
The understanding of traits being retained or lost in populations in evolution is important, but what are the mechanisms that describe how traits stay or leave?
