What is the original source of all variations in heritable traits?
The original source of all variations in heritable traits is genetic mutations. Mutations are changes in the DNA sequence that can create new traits or alter existing ones, providing the basis for genetic diversity within a population.
Why aren't all mutations bad?
Mutations are unnatural changes in the body or behavior. They are not always bad. For instance, the skin of the poison tree frog is not really bad at all. It rubs itself on poison leaves and mutated itself not to be affected.
Will cells with mutations always make normal proteins?
Cells with mutations may not always produce normal proteins. Mutations can alter the DNA sequence, which may result in changes to the structure or function of the protein produced. These changes can lead to abnormal protein function, which can impact cellular processes and potentially contribute to disease.
Are all mutation harmful?
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.
What is the relationship between genetic variations and mutations?
Mutations are random changes in DNA; genetic recombinations are new arrangements of genetic material (as a result of sexual reproduction). Together, they are the "fuel" that powers the "evolution machine," the direction of which is determined by natural selection.

Can mutations cause changes in DNA sequences?
mutations
Is the following sentence true or false all mutations are harmful?
False. Not all mutations are harmful. Some mutations can be beneficial or have no effect on an organism. Mutations are simply changes in the genetic material of an organism, and their impact on an organism's traits can vary.
Can you get Pokemon mutations such as mewtrance in soulsilver with an action replay code?
Pokemon mutations are not part of the game at all. Pokemon mutations are a result of hacking by an action replay.

Mutations that occur in germ-line cells are?
Somatic mutations occur in somatic body cells. These mutations are passed on to daughter cells during mitosis and to the offspring of those cells in turn, but are not passed on to sexually produced offspring.
Are all mutation harmful?
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.

Describe how gene mutations affect protein production.?
gene mutations can affect protein production through various mutations as nonsense mutations are any genetic mutation that leads to the RNA sequence becoming a stop codon. missense mutations are mutations that changes an amino acid from one to another. Slient mutations are mutations that dont affect the protein at all.
Why all mutation are not necessarily harmful?
Mutations are changes in DNA. Most are neutral or beneficial. Mutations have allowed animals to adapt to new environments and new species to evolve.
Difference between heritable and non heritable variation?
Some characteristics like hair and eye colour, whether or not you can curl your tongue, your height, skin colour are all things that you inherit from your parents, also why you look like them. Other characteristics are not inherited, but could be a result of your surroundings. For example, fetal alcohol syndrom is not inherited from your mom, it is a result of your mom drinking when pregnant. Many birth defects in babies back in the 50's and 60's was a result of mothers taking thalidamide, a drug used to prevent morning sickness, a non-heritablecharacteristic!
