What Are Genetic Variations Caused By The Environment
Evolution, Genes & the Environment
Variation is when you refer to genes; it means that there is a large variety of phenotypes, alleles and genotypes which can sometimes cause genetic variation. This results in different physical characteristics.
Some examples of variations in humans are eye colour, hair colour and gender.
Variations caused by the environment are the climate (tanned/pale skin) this is affected by the environment as the sun comes in contact with your skin and will darken it, the language that you speak as when you are young, you are impacted by the individuals that raise you and their language will rub off on you as you are constantly hearing it, your diet (thin/big) becoming bigger is caused by an overwhelming amount of food at your finger tips (MEDC) or you could become thin if you live in a LEDC as there is not a great quantity of food available at hand and maybe a physical accident (leaving scars on your skin possibly) and this could occur by the impact of your surroundings e.g. car accidents, war and animal bites. …show more content…
Variations caused by genes are eye colour (blue, hazel or green) which is passed on from our parents, hair colour (blonde, ginger or brunette) this is passed on through are parents.
Variations caused by both the environment and genes are skin colour which can be impacted by the sun or it could be passed on from your parents, hair colour which could be passed on from your parents or the sun could help change the lightness of your hair and weight as you can be born with a weight disorder or you could put on weight by eating too
much.
Genes are transferred from a parent to offspring and is held to determine some characteristic of the offspring e.g. brown hair which could of been transferred from either your dad’s/mum’s genes; chromosomes are a structure of DNA that is organized and found in the cells is protein, a chromosome is DNA that is a single piece of coil which contains many genes. DNA is acid that is nucleic and carries genetic information in a cell; it consists of two long chains that are twisted into a double helix. DNA is a double helical structure that is made of nucleotides that are molecules and DNA is found in a cell’s nucleus e.g. adenine, guanine, thymine, and cytosine.
Genes cause variations by crossing over and exchanging chromosomes; this will randomize the information that each chromosome obtains which will make a variation. E.g. a different shaped nose.
Eye colour e.g. Brown eyes and blue eyes are the alleles that are represented by ‘B’ and ‘b’. ‘B’ represents the dominant (brown) allele and ‘b’ represents recessive (blue) allele. This cross produces offspring with all brown eyes but carriers of blue alleles.
An animal that has changed over hundreds of years would be a chimp transforming into a human. Fig.1 is an example of the development: http://absoluteprimacyofchrist.org/appendix-ii-creation-of-adams-body/ Genes cause animals to change to help them adapt to the environment around them in a more efficient way which meant due to the gene mutation, it resulted in tall giraffes E.g. all giraffes can reach the branches but the lower branches started to die off which means the smaller giraffes wouldn’t be able to reach them braches resulting in the smaller giraffes to die off. This means that the medium/tall sized giraffes will begin to breed with each other causing the new breed to never become small which has a final outcome of the giraffes now being medium/tall sized.
The industrial evolution (environment) started to produce large volumes of pollution which resulted in the trees to become black, this impacted the peppered moth as it is a pale brown colour and used the bark of the trees to camouflage. This means that the moth is now visible and will be eaten by its predator (birds). Although, there was a rare darker shade of brown moths which means that they will survive to breed and become the most common type of moth. This will show the changes in the environment can cause variation within a species.
Random genetic mutations result in variation as them random genetic mutations will be passed on when the holder is breeding which results in a variation.
A genetic mutation is a change in the gene which can be caused by the environment e.g. pollution added to the ocean could cause fish to have a genetic mutation which will be passed on when the fish are breeding.
A genetic mutation can be linked to the environment as it can help the organism to survive in their environment as the genetic mutation could cause the organism to change colour helping it to camouflage. E.g. a fish could change colour from yellow to green which means the fish could possibly camouflage in with the coral.
Mutations can lead to extinction as the mutation could change the colour/pattern of the animal which could result in the animal not being able to hide from their predators as they cannot camouflage in with their original environment; this results in that animal dying off and creating a higher chance if that animal to become extinct.
