- Humans manipulate the genetic code in the DNA for a number of reasons
- The first is to ensure the survivability of future generations of the human population and that they are healthy and benefit the population. Therefore, minimising the risk of passing on faulty alleles to future generations that causes genetically caused diseases such as cystic fibrosis. Having genetically cause diseases leads to a low life expectancy, increased health issues in the population which could be increased if the amount of faulty alleles were to increase in the population naturally and the number of beneficial alleles were to decrease in the gene pool without any interference by humans and it will not beneficial to the population, therefore is why human manipulation …show more content…
In order to get cystic fibrosis, the offspring must have received the mutated “CFTR” allele from both parents, meaning that they have 2 of the faulty alleles, which therefore causes cystic fibrosis. If only 1 of the mutated alleles is inherited by the offspring they do not have cystic fibrosis because they do not have 2 of the mutated CFTR alleles in order to cause cystic fibrosis, even though they do not get cystic fibrosis they will still be able to pass the allele onto their offspring, as their mutation is in the gamete cells and is not just present in the somatic cells (which can’t be given to offspring) and if their mate has the same mutated allele, their offspring may have cystic fibrosis if both parents give the mutated gene to the offspring or a carrier if only 1 parent has it and passes on the mutated CFTR allele. Even if both parents don’t have cystic fibrosis themselves, they still be considered ‘carriers’ of this allele for the gene because their offspring and future generations may still be able to get cystic fibrosis. This means that cystic fibrosis can’t be passed between large groups of individuals of the same species like the flu because not everyone may have had inherited the 2 mutated CFTR alleles from their parents as cystic fibrosis is a genetically inherited …show more content…
This is beneficial as there is no choice in which sperm will fertilise the egg when fertilised naturally and the genetic content of that sperm, which could mean a mutated allele such as CFTR could still be given to the offspring. This screening is done after the fertilisation of the egg and sperm but before it is placed in the female. This is done at this time because the embryo has all of the DNA that the offspring has and so
