Gene Shuffling
Sex can introduce new gene combinations into a population and is an important source of genetic
A sexual cycle is maintained because it improves the quality of progeny.
Advantage of Gene Shuffling
• Sexual reproduction can bring together mutations
• Can be beneficial into the same individual
• Unfit individuals that are then eliminated from the population
• Sex creates new gene combinations that may be more fit than previously existing ones
Genetic variation happens because of new gene combinations occurred due to sex. It is an important source of population. Normally in humans
The children must have both characters from parents like eye color, eyebrow shape, hair color, nose shape, body color, voice, height, etc… After this shuffling the result may be great, normal, or worst.
This shuffling is important for evolution because it introduces new gene combinations in each generation. But it may reduce the good combinations and increase the normal or bad combinations. It is totally based on the chance of gene combinations.
Development
After the fertilization, once the embryo developed in to adult organisms its genotype is expressed as a phenotype. These external appearances of the organism help us to understand the new combinations easily. It is the basis of evolutionary biology.
Shuffling Genes Without Sex
Asexually reproducing organisms maintain variation in their DNA. Female whiptail lizards can actually double their own chromosomes during meiosis, according to a study published in Nature.
Parthenoge
But since gametes in these species only receive one set of chromosomes, researchers have wondered how offspring maintain genetic diversity, especially in more complex vertebrate species.
Change in Morphology
Gene shuffling may result with major effects in the morphology of the organism. Because of gene shuffling fruit flies evolved with two pairs of wings instead of one. Developmental processes may prevent certain characters from evolving in certain lineages.
