What are defective genes?
Defective genes are genes that have mutations or alterations that can lead to abnormal function or health conditions in individuals. These mutations can disrupt the normal processes controlled by the gene, potentially resulting in genetic disorders or diseases.
How can science prevent implanted genes from being passed on to the next generation?
Only by not implanting the genes in the first place. Once implanted, the genes will be passed on to future generations. If the implanted genes corrects a medical defect and future generations don't suffer from the same defect, then implanting genes could be classed as a benefit to mankind.
What is the definition of life history pattern?
Life History Patterns - optimization of traits that maximize the passing of genes on to future generations.
What type of theorist believes that all humans instinctively try to ensure their genes are passed on to future generations?
conflit theories
How does recombinant DNA replace defective genes?
well it helps it
Gene therapy which includes the correction of defective genes is a significant part of the human genome project. Which of these is an application of the technique?
a new gene which codes for the protein that can repair defective genes is introduced.
What is the success of an organism in passing on its genes to the next generation called?
This is called "reproductive success". It refers to an organism's ability to produce offspring that survive and reproduce themselves, thus passing on their genes to future generations.
Vaccines can now be genetically engineered by inserting the genes that encode the pathogen's surface proteins into the what?
the RNA of the defective genes
How does natural selection enhance or reduce tha variability of a species?
Natural selection 'weeds out' defective genes through successive generations - this both enhances a species chances of survival, and reduces variations in the species genetic make-up.
What is a pathological condition caused by absent or defective genes?
That is the definition of a genetic disorder.
Why do many inherited conditions result from defective enzymes?
Inherited condition result from defective enzymes because enzymes are proteins and genes encode them.
Why do insecticide resistant organisms develop?
Evolution. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent generations. A trait that increases survival rate (resistance to an insectide) is passed on more frequently than a trait which is detrimental to procreation.
