Say that when humans move to other planets, none of them will have the same gravity as earth. That means that shorter, more thickset people will be better able to live on a high gravity planet (for obvious reasons.)
If taller, thinner people (like me) went on the same world, we would be uncomfortably pulled down, and if we fell down we would break our thinner bones.
However, if a short, thick-ish person fell over, he would have a tiny distance to fall and, having stronger bones because of the extra weight he was carrying, be better able to absorb the fall.
BRCA1 and BRCA2 mutations increase the risk of breast and ovarian cancer in women. Women with these mutations have a higher lifetime risk of developing these cancers compared to those without the mutations.
mutations in dna can be advantageous and lead to charecteristics that help a person survive or increase it chances of survival.
No, not all mutations are harmful. Some mutations may result in new traits that provide a survival advantage, while others may have no effect on an organism's fitness. Additionally, some mutations are neutral and do not impact an organism's health or survival.
Mutations can have various effects on living organisms, ranging from no visible impact to causing genetic disorders or changes in physical traits. Beneficial mutations can lead to evolution and adaptation, while harmful mutations can reduce an organism's fitness or survival. The specific impact of a mutation depends on factors such as its location in the genome and the nature of the genetic change.
Mutations can lead to changes in an organism's DNA, potentially altering its physical traits, functions, or behaviors. They can be beneficial, harmful, or neutral, depending on the environmental context and their effects on the organism's survival and reproduction. Over time, beneficial mutations can contribute to evolution by providing advantageous traits that enhance adaptability. Conversely, harmful mutations can lead to diseases or decreased fitness.
Mutations can be both helpful and harmful. Beneficial mutations can lead to adaptations that increase an organism's chances of survival or reproductive success, while harmful mutations can lead to genetic disorders or reduced fitness. The role of mutations in evolution is complex and depends on the specific environment and genetic context.
Yes
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
The majority of permanent genetic mutations are considered to be neutral. This means that they do not have a significant impact on an organism's fitness or survival.

No, not all mutations are harmful. Some mutations may result in new traits that provide a survival advantage, while others may have no effect on an organism's fitness. Additionally, some mutations are neutral and do not impact an organism's health or survival.
Some mutations persist in a population due to their beneficial effects, enhancing survival or reproductive success, which increases their frequency through natural selection. Conversely, harmful mutations may be eliminated from the gene pool as individuals carrying them have lower fitness. Additionally, neutral mutations can become fixed by genetic drift, especially in small populations. Overall, the fate of a mutation depends on its impact on fitness and the population structure.
Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection. Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
False.
Mutations can result in harmful effects by disrupting important genetic functions or causing diseases. They can also be beneficial by creating new genetic variations that increase an organism's chances of survival in changing environments. Some mutations may have neutral effects, meaning they do not significantly impact the organism's fitness or health.
