Genetic Variability: Within the same population or species (loosely defined as a group of organisms that can mate and reproduce fertile offspring), there are differences, some expressive and some non-expressive, in the genome of the species. Measuring and identifying such variations is important to...
Which of the following ways is most likely to decrease the genetic diversity in a population ? (a) Gene mutation (b) Genetic recombination (c) Stabilising natural selection (d) Immigration of individuals View Solution (a) What is a genetic code ?
Multidimensional is intelligence consisting of different aspects derived from experiential, environmental and genetic influences. Multidirectional change is defined as differentcognitive dimensions will alter, over time, independently or dependently of each other. What is individual difference theory? A theory ...
though it is certain that it will be possible. If so, parents of the future may be able to choose which of their genes are inherited by their children, or even introduce entirely new traits into their genetic lineage.
at specific places in the genome. For example, most individuals carry the C nucleotide at a specific base position in the genome, but in a minority of individuals this is replaced by an A. This means there is a SNP at this specific p...

This has given us a greater understanding of the genetic aetiology of psychiatric disorders and how they are biologically related to each other. How this information can be translated to the clinics, can now be considered. Genetic testing in psychiatric disorders, is currently possi...

This means that the variations we see are not due to their genetic makeup, even though pigmentation is the result of their genes. In such a case heritabilty is zero.At the other extreme we have a population with many variants of the pigmentation gene, but everyone spends all day outside...
